RA8806
Preliminary Version 1.2
Two Layers Character/Graphic LCD Controller
1. General Description
RA8806 is a LCD controller for Dot-Matrix type STN-LCD which supports both character and graphic mode
display. The RA8806 has built-in two Display Data RAM(DDRAM) for two layers display, and has an
embedded font ROM which is capable of displaying the full-size(16x16 pixels) traditional Chinese font(BIG5,
13973 characters) or simplified Chinese font(GB, 9216 characters). RA8806-J is one controller in this series
that consisting of Kanji and Hiragana according to the JIS standard Level-1 & 2 Kanji font (6,355 characters).
RA8806 also contains 4x256 embedded half-size (8x16 pixels) characters that can display ISO8859-1 ~ 4(or
called Latin-1 ~ 4) alphabets using at most of English speaking and Europe countries.
RA8806 supports 8080/6800 MPU protocol interface, which is capable of switching the interface with 4-bits
or 8-bits data bus. For LCD driver interface, it can be set to 4-bits or 8-bits data bus. The maximum
resolution of RA8806 is 320x240 pixels in normal mode, and 640x240 or 320x480 pixels in extension mode.
By using the font rotation mode, which can implement the “vertical” font display. The embedded intelligence
touch panel controller provides the 4-wires resistance-type Touch Panel interface. The PWM output
provides an easy contrast or back-light control method for LCD panel. RA8806 also provides a 4x8(32 keys)
or 8x8(64 keys) powerful and smart Key-Scan interface includes long-key function. The flexible interrupt and
polling mechanism can make it easy to control touch panel, key-scan and power mode functions. Also it can
greatly reduce the MPU loading. The embedded 512Byte character generation RAM (CGRAM) allows user
to build maximum 16 full-size or 32 half-size fonts. Even with the single layer display, the other unused layer
can be used as CGRAM too. In this setting, the amazing 300 full-size and 600 half-size user created fonts or
symbols are supported.
In addition, RA8806 supports 4-gray-scale display in FRC mode. The bit-arrangement is compatible for most
gray level picture and easy to program. RA8806 also includes many useful functions, like area scroll, font
inverse, font bold, font enlargement, memory clear function and so on. An innovative mechanism of “noflicker” mode is provided in RA8806. It’s effective for removing the “flicker” in frequently display data
Read/Write. User can easily improve the display quality by RA8806.
RA8806 is a powerful and flexible LCD controller. It provides the total solution for the middle-size mono LCD
controller. User can save large amount of time for system development and the cost of hardware system.

6-1
MPU Interface
6-1-1 MPU Type
The RA8806 support 8080 or 6800 compatible MPU interface. When the pin “MI” is pull low then the
MPU interface is set to 8080 compatible. If “MI” pulls high then the MPU interface is defined as 6800
compatible. And the pin “DB” is used to select the 8080 MPU data bus is 4-bits or 8-bits. When “DB”
is pulled low, then the data bus for data transition is 4-bits. If pin “DB” pull high, the data transition is
8-bits. The option of 4-bits or 8-bits data bus is for both 8080 and 6800 MPU. Of course, if used 4bits interface then the 8080 MPU has to take double time to communicate with RA8806. In order to
reduce the transmission line interference between MPU interface and RA8806, we suggest that a
small capacitor to the GND should be added at the signal of ZCS1、ZRD、ZWR, please see the
following Figure 6-1.

6-1-2 Command Write
According to the Table 5-1, RA8806 accept 4 cycles through MPU interface. If users want to write
command to RA8806, then a Command cycle has to execute first, and then execute a Data Write
cycle. The “Command Write” means write function data to register. After these two cycles, the Data
will write into the indicative Register. Please see the following Figure 6-5 (1).
In Table 6-1 of Section 6-1-1, each command of RA8806 is take 2 cycles, and the minimum cycle
time is 2*tc. So totally the minimum time of command write need 4*tc. See following Table 6-3.
If the secondary cycle is a “Data Read”, then user could read the register content. See the following
Figure 6-5 (2). Note the Figure 6-5 to Figure 6-7 are use the 8080 MPU interface as examples.

6-2-1 Display Resolution
RA8806 support many different resolution of LCD panel. For different resolution of panel, RA8806
could change the setting of some registers like DWWR and DWHR to modify display window size.
And use registers AWRR, AWBR, AWLR and AWTR to change the active window size.
For example, if 320x240 LCD panel is used, then the related register setting is as following:
DWWR = (320 / 8) - 1 = 39 = 27h
DWHR = 240 – 1 = 239 = EFh
The active window range is less than display window. So user has to care the rule as following:
1. DWWR ≥ AWRR ≥ AWLR
2. DWHR ≥ AWBR ≥ AWTR
RA8806 supports a variety of LCD modules, the setting of register depnding on different resolution
of LCD module is list at below table.

6-2-4 Idle Time Counter (ITCR)
ITCR(REG[90h]) is used to determine the idle time during the LP peer-to-peer time. It has following
meanings in function.
1. Adjusting the Frame Rate.(By extending the scan time of each COM)
2. Avoiding the generation of “Flicker”.
The “Flicker” is generated by the violation of LCD scan cycle and Memory write cycle. “Flicker”
means the noise of the scan data at such violation. By setting the ITCR, user can write the display
memory only at “Idle” time to eliminate the “Flicker”.

COM_PRD = ((SEG_NO/LD_WIDTH) x (1 + EXT_MD)) ＋ ITCR ) x XCK_PRD
In which the EXT_MD means extension mode is set or not, if REG[12h] Bit[6:4] = 110b/111b,
EXT_MD = 1, or EXT_MD = 0. The “XCK_PRD” is one clock period of XCK. The XCK frequency is
base on the system clock. It depends on the setting of Bit[3:2] of REG[MISC]. As to the Frame time
and frame rate calculation. It would be:
FRM_PRD = COM_PRD x COM#
And
FRM_Rate = 1 / FRM_PRD
For example, when panel size is set to 320x240, system clock frequency is 8MHz, REG[MISC]
Bit[3:2] = 10b, LCD driver data bus width is 4-bits, what the frame rate would be?
The System Clock(CLK) is 8MHz, and REG[MISC] Bit[3:2] = 10b Æ XCK = CLK/2, so the XCK_PRD
is 250ns.
XCK_PRD = 1 / (CLK/2) = 1/4MHz = 250ns
COM_PRD = ( 320 / 4 ＋ ITCR) x XCK_PRD = (80+ ITCR) x 250(ns)
If the ITCR = A0h(160 in decimal):
COM_PRD = (80+160) x 250ns = 240 x 250ns = 60µs
The COM number is 240, so the frame period is:
FRM_PRD = 60µs x 240 = 14.4 ms
And the frame rate is:
Frame Rate = 1 / 14.4 ms = 69.4 Hz
We can see the effect that the ITCR setting to the corresponding frame rate. So we can use it to
adjust the frame rate. Please refer to Appendix B - the Table B-1 ~ Table B-3. In those tables, we
show some Frame Rate setting for difference resolution, system clock. But note the display quality is
also depends on the module design and the material of liquid crystal.

layers mono-display or one layer 4-gray-levels display. The maximum resolution of supporting LCD
panel is 320Column x 240Row. There are two modes to write the DDRAM, text mode and graphics
mode. It provides a flexible and easy way to make the display.
6-3-1 Display Layer and Display Mode Selection
There are 4 possible displays way at 2 Modes combination.
1. Only show DDRAM1 or DDRAM2: One DDRAM data will show on the screen, and another one
DDRAM can be standby or as a CGRAM to created special font or symbol by users. Please refer
to Section 6-11 “User Defined Font” for detail description.
2. Two Layer Mode: In this mode, the screen will show the combination data of DDRAM1 and
DDRAM2. There are 4 types combination that set by REG[12H] Bit[3:2].
DDRAM1 “OR” DDRAM2
DDRAM1 “XOR” DDRAM2
DDRAM1 “NOR” DDRAM2
DDRAM1 “AND” DDRAM2
For detail please refer to Section 6-10-1-5 “Two Layer Display”.
3. 4-Gray-level Mode: In gray mode, each pixel consists with 2 continuous bits in both DDRAM.
4. Extension Mode: Two extension modes is support, and both DDRAM1 and DDRAM2 data will

Touch Panel
RA8806 built in a 10-bit ADC and control circuits to connect with 4-wires resistance type touch panel.
Resistive Touch Panel is composed of two layer extremely thin resistive panel, such as Figure 6-16.
There is a small gap between these two-layer panels. When external force press a certain point, the
two-layer resistive panels will be touched, which is short. Because the end points of two-layer have
electrodes (XL, XR, YU, YD), such as Figure 6-17, a comparative location will be detected with some
switches in coordination.

Users only need to connect the touch panel signals -- XL, XR, YU, and YD to RA8806. It will
continuously monitor the panel and wait for touch event. When the event is occurred, a divided voltage
on panel caused by touch is sensed and transferred by ADC to determine the location. After the value of
X-axis and Y-axis are transferred and stored in corresponding registers respectively, the touch panel
controller will issue an interrupt to inform MPU to process it.

6-4-2 Manual Mode
The “ Manual Mode” means that the operation process from “Touch event checking function” to
“input Latch X data Y data”, the whole operation and setting process ( includes TPCR2[1:0]) and
receiving data from XY coordinates are manual operated by programmer. The advantage of using
Manual Mode is it allows programmer more flexible applications. In the condition that is over the
range of RA8806 register setting, the user can still use the software method to control the TP
function in a correct way.
Touch Event can be detected from “Interrupt Mode” or “Polling Mode” that depend on the system
configuration. The difference between the “Interrupt Mode” and “Polling Mode” are explained as
following.
6-4-2-1
External Interrupt Mode
Under the “Interrupt Mode” the touch event detecting way is almost the same as “ Auto Mode”. The
major processes are list as follows:
1. Enable Touch Panel function.
2. Change mode to “Manual mode”.
3. Set the switch to 「Wait for touch event 」, Set TPCR2[1:0] to 01b.
4. When interrupt asserts, check if TP interrupt.
5. If yes, change the switch to 「Latch X data」, Set TPCR2[1:0] to 10b, wait for enough time
to make the latch data stable and latched to TPXR and TPZR.
6. Change the switch to「Latch Y data」, Set TPCR2[1:0] to 11b, wait for enough time to
make the latch data stable and latched to TPYR and TPZR.
7. Read X, Y data from TPXR, TPYR and TPZR, and clear the interrupt status.

Polling Mode
Under the ”Polling Mode”, users need to decide and set the de-bounce time after the touch event, as
well as the sampling time after latch by considering the real situation, thus more flexibilities for users
apply this mode.
The development procedures are explained as follows:
1. Enable Touch Panel function
2. Change mode to “Manual mode”
3. Set the switch to「Wait for Touch event」, i.e., set TPCR2[1:0] to 01b.
4. Read Touch Panel Event status from status register, check if the “Touch event” happens.
5. When touch event happens, confirm the stability of it and set the switch to 「Latch X data」,
i.e., TPCR2[1:0] set to 10b, wait for enough time to make the latch data stable and latched
to TPXR and TPZR
6. Set the switch to「Latch Y data」, i.e., TPCR2[1:0] set to 11b, wait for enough time to make
the latch data stable and latched to TPYR and TPZR
7. Read X, Y data from TPXR, TPYR and TPZR, and clear the interrupt status

Programmer can check the status of Touch Panel Event from the Bit-3 or Bit-0 of INTR, the
difference between those two bits is :
1. The Bit-3 of INTR reflects the current Touch status. When Touch event occurs, the Bit-3 is 1.
When there is no Touch event, Bit-3 will be 0 and read only.
2. The Bit-0 of INTR records the Touch status. When a Touch event occurs, the Bit-3 will be 1
and however it won’t be clear automatically, it has to clear by programmer.
It needs to be noted is that the REG[0Fh] Bit-3 is the direct output from ADC circuit, when touch
panel is touched, the bit will respond with the event. When touch event is not stable, it needs to be
de-bounced to check if it’s legal. The bit is only active at “Manual mode”. When setting RA8806 to
“Auto-mode, the touch event will be automatically checked if it’s legal or not. Only the legal touch
event will cause the interrupt.

6-7-4 Sleep Mode
The RA8806 provide two operation modes: Normal mode and Sleep mode. Please refer to Chapter
5 “Register Description” for Register WLCR explanation. RA8806 will shut down the system clock, to
achieve the minimum power consumption. When RA8806 is under the Sleep mode, only the status
register can be read, other registers are not allowed to read. Other command besides REG[00h] Bit7(Sleep mode) can’t be written. When RA8806 is under Sleep Mode, it can accept the following
three methods to wake-up.
1. Write REG[00h] Bit-7 = 0, then it will return to Normal Mode.
2. Touch event is detected.
3. Key-Scan is detected.
When RA8806 quit from Sleep mode, to avoid the incorrect activity, RA8806 must de-bounce the
wake-up event for enough time(about 1,000 system clock periods) to make sure it, then quit from
Sleep mode.
Besides, when MPU program RA8806 to enter Sleep mode, RA8806 can’t receive command from
MPU anymore till quit the Sleep mode. The command will be lost. User program must avoid the
possibility of the condition. For example, if RA8806 be programmed to Sleep mode, at the same
time, the MPU receives an external interrupt, and cause the MPU enter the Interrupt Service
Routine(ISR). That will cause RA8806 can’t correctly receive and recognize the command.
From the view of hardware design, the condition can’t be prevented. Because the external interrupt
is an individual mechanism of MPU. We can’t predicate the happen of it from the role of RA8806. It’s
a possible risk even the possibility is rare.
So it’s suggested that MPU must be mask the interrupt for RA8806 before commanding the RA8806
to enter the Sleep mode. The interrupt mask is off after RA8806 quit from Sleep mode. Besides,
because the status register can be read normally at Sleep mode. Also user can check the status in
the ISR for judgment. If RA8806 is checked under Sleep mode, MPU can quit ISR and execute
nothing to prevent incorrect activity.

Two Layers Character/Graphic LCD Controller
Interrupt and Busy
The RA8806 provides an interrupt output (INT) for MPU to indicate the status of RA8806. And a busy
output to indicate the RA8806 is in busy state. Both signals could be set to active high or active low by
register.
6-8-1 Interrupt
RA8806 provides an Interrupt signal (INT) for following event:
‹
Touch Panel touched event is happen.
‹
Key-Scan enable and key is pressed
‹
Wake-up event occurs when Sleep mode.
These interrupt events can be masked or active respectively. It is controlled by the REG[0Fh], the
mask and status registers.
Besides, RA8806 also provide a software access interrupt function. When user system don’t support
hardware interrupt signal, they can use polling method to achieve the software interrupt.
To access hardware interrupt, user needs to set corresponding Interrupt Mask bit to 1(Refer to
register INTR). The steps are:
‹
RA8806 generate the interrupt signal to MPU.
‹
After finishing the current instruction, MPU hardware will jump the PC(Program counter)
to Interrupt Service Routine(ISR).
‹
In the same time that RA8806 generate the interrupt, the interrupt status is set
to ”1”(REG[0Fh] Bit[2:0]). (For example, if key-scan interrupt activates, the Key-Scan
status will be set to 1).
To apply the software interrupt method, users don’t need extra setting. Just reading the status bit of
register INTR to check the interrupt event. BTW, interrupt mask can only disable the hardware
interrupt, but can’t disable the status of INTR.
Example-1:
The Figure 6-32 is an example of INT timing for Wake-up event. RA8806 provides three wake-up
event. Please refer to Section 6-7-4 “Sleep Mode” for the detail.

t INTST = Clock Stable Time + 1024*t C
If user use a 6MHz X’tal for system clock, the Clock Stable Time is about 3~3.5ms and t C is 167ns.

The “De-bounce Time” is set by REG[A0h] Bit[5:4], and the tCKEY is the Key-Scan Cycle that
depends on the setting of REG[A0h] Bit[2:0].
Additionally, because the status bit will not be cleared to 0 automatically. So user must manually
clear it after processing the interrupt routine.
6-8-2 Busy
The RA8806 also provides a “BUSY” signal. When Busy Flag is “1”, which means RA8806 is in busy
state that RA8806 couldn’t access data from DDRAM. Two busy conditions are provided. One is
Scan Busy and another is Memory Write Busy. The detail explains is as follows.
Scan Busy:
When LCD panel displays, RA8806 scan circuit will access the DDRAM. If another DDRAM access
cycle happens. It will cause the data lose in one of them. So when scan circuit is active, it causes a
busy condition, called Scan Busy. Figure 6-34 shows the data flow diagram of scan circuit and MPU
memory access cycle. Figure 6-35 is same as Figure 6-15 to show RA8806 scan waveform. It
describes the condition that RA8806 scan the display for each COM line. The COM scan time is
combined with an Idle time and a Scan time. The Idle time period can be set by register ITCR. The
Scan period is the time of Scan Busy. Also accessing data at Scan Busy time will cause the scan
data lose. But it will not cause a fatal error. The scan data lose will cause the display defect. But if
it’s not too frequent, the defect will not infect the display too much.

Memory Write Busy:
Following two conditions will cause the Memory write busy:
1. When MPU write data in text-mode. Depending on different size of font, it needs an enough
time to write the font to DDRAM. At the period, RA8806 can’t access the DDRAM again, it’s
a memory write busy condition.
2. When MPU program RA8806 as a memory clear function(FNCR Bit-3 = 1). The period of
clear DDRAM also cause a memory write busy.
It will cause the DDRAM lost when accessing DDRAM in the period of Memory Write Busy. So user
must check the busy status after the upper two conditions is done.
Besides, RA8806 provide polarity setting for “BUSY” and interrupt “INT” pin. (Please refer to register
MISC)
Normally, this “BUSY” pin is connected to MPU I/O input, and then MPU have to monitor this pin
before accessing RA8806. The following is the timing of BUSY pin. The BUSY can be active high or
low that depend on the setting of REG[01h] Bit-5.

There are two modes for MPU to write data to RA8806, i.e., character mode and graphic mode. In
graphic mode, data is written directly to DDRAM in bit-map format. In character mode, data is
written in code format, the font bit-map in the CGROM will be written to DDRAM by this way.
RA8806 stores two different sizes of characters in its font ROM - 1) half size font(8x16 pixels), 2) full

The RA8806 provide an Auto-Write feature to fill a data to all of the DDRAM. At first, user writes the
data to Register PNTR then initials the Auto-Write function(Register FNCR Bit-3). RA8806 will fill the
data to DDRAM in very short time. Normally this feature is used to clear screen or want to fill fixed
pattern or background on screen.

There are three types of CGROM in RA8806, i.e. RA8806-S, RA8806-T and RA8806-J. RA8806-S
contains the Simplified Chinese characters with the coding of GB standard. RA8806-T contains the
Traditional Chinese characters with the coding of BIG5 standard. RA8806-J contains the JIS
Japanese Kanji Level 1 & 2 font characters. About the detail, please refer the Appendix D, Appendix
E, and Japanese Kanji font code table (RA8806_DS_V12_Font_JIS.pdf).

The RA8806 displays the Chinese characters in text mode. Key in the Chinese code (GB or BIG5
code) directly , then it will display the Chinese characters in cursor position. If display Chinese ,
RA8806-S accepts the GB code, RA8806-T accepts the BIG-5 code. The Chinese character
occupies two Byes, hence the MPU should write the Chinese code (High Byte & Low Byte) separate
into RA8806 in case the MPU interface is 8-Bit. The English code or numeric code occupies only
one Byte, hence it will write the code into the RA8806 at a time. i.e. for RA8806-T, the BIG-5 code of
character ”世” is “A540”, MPU will send the “A5” and “40” in proper order to RA8806-T, then it will
display the Chinese character of ”世”.
If use the Japanese Kanji font version of RA8806, that is RA8806-J, it should transfer the JIS code
for a start , then the MPU send the code to RA8806-J. Firstly, add 80h to the Hi-Byte of JIS code,
then to judge the Low-Byte, if it is larger or equal to 60h, then adds 40h, otherwise adds 20h. Then it
will display the Japanese Kanji font if the new code sends to RA8806-J by MPU. i.e. the JIS code of
character ”粟” is “3040”, to transfer to the new code is “B060”, to send the “B0” and “60” in proper
order, then it will display the Japanese Kanji font of ”粟”.
The Font ROM of RA8806-J mainly refer to the coding of JIS code, if the user use Shift-JIS code
(called for short S-JIS), then it should be transfered by another procedure, firstly, transfer S-JIS
code to JIS code. It is in common use of S-JIS coding for Japanese computer system, because it
contains the full font and half font of Latin character, Hiragana, Katakana, notation and the
Japanese Kanji font. It is named by Shift_JIS, for put in full font, to avoid put in the 0xA1~0xDF of
the Half-width Katakana.
The Figure 6-43 is the flow chart for the S-JIS code transfers to JIS code and JIS code transfers to
RA8806-J, furthermore the attachment is the program for the user to refer. i.e. the S-JIS code of
character ”粟” is “88BE”, transfers to JIS code is “3040”, as the description above, JIS transfers new
code to “B060”, then send “B0” and “60” in proper order to RA8806-J, it will display the Japanese
Kanji font of ”粟”. i.e. the character ” 甌” of J-JIS code is “E14D”, transfers to JIS code is “612E”, as
the mention above, the JIS transfer new code to “E14E”, then send “E1” and “4E” in proper order to
RA8806-J, in the meantime display the Japanese Kanji font of ” 甌”.

After writing completed font code(One byte for half size font and two bytes for full-size font), it will
takes an enough time for data to be written into the DDRAM. In the mean while no data can be read
or wrote into DDRAM. (Please refer to Section 6-8 “Interrupt and Busy”, the description of “Memory
Write Busy”). The writing time is differing from the enlargement multiplier of font size. Its calculation
formula is as follows :
Tfw = ( 16*tc + 32*tc x ( HW x VH ) ) x ( 1 + 10% )
Tfw : Font Write time
tc
: System clock period
HW : Horizontal enlargement multiplier.
VH : Vertical enlargement multiplier.
Here 10% is for the flexible error consideration. Please refer to the following examples: (Estimate
the system clock is 4MHz and the tc is 250ns)

RA8806 features of its “Font Vertical Display” function. This function enables the normal display
change to vertical display. This means the original 320x240 panel can be used as a 240x320 panel
to display embedded character font or data in vertical way, and no need to change scan direction or
the LCD driver layout. The LCD panel could display from both vertical and horizontal ways. This
function is option on setting the Bit-3 of register WCCR. When WCCR Bit-3 =1 (Font Rotation Mode),
the font character will be written in vertical display. Figure 6-51 shows the example of font vertical

Due to the advance rotate function, if user chose a 240x160 module, then it will be very easy to use
same module but as an 160x240 module. The following Figure 6-52 shows the example of 320x240

2. For created full-size font, after CURY is assign(0~15) and CURX is set to 0, a created-font
bit-map can be filled by the 32 continuous memory writes cycle. And then CURY will be
increased by 1. Please refer the following Program Example(1). The result is show (1) of
Figure 6-53 on screen.
3. For created half-size font, after CURY is assign(0~15) and CURX is set to 0(odd font) or
10h(even font), a created-font bit-map can be filled by the 16 continuous memory writes cycle.
Please refer the following Program Example(2). The result is show (2) of Figure 6-53 on
screen.
4. The CGRAM font code is 8F00~8F1F for Half-size font, and 9F00~9F0Fh for full-size font.
Refer to Table 6-31.

The DDRAM are 9.6KByte RAM, so it could create 600 Half-Size or 300 Full-Size characters. Table
6-35 is the font code mapping table in DDRAM for Half-Size characters. Table 6-36 is the font code
mapping table in DDRAM for Full –Size characters. These font codes were also fix in RA8806. The
register CURX and CURY are used to point the address that bit-map data to create font.

6-11-3 Create Symbol
RA8806 provides font creator function that allows user to design and create new fonts, special
symbols or logos and store into its embedded CGRAM or DDRAM. The user-created characters
each defined as a full-size (16x16) or half-size (8x16) character bitmap font formats, thus 24x16,
40x16, 16x32 or bigger sized fonts are also possible to create accordingly. The following Figure
6-56 represents a user created symbol with size 24x16.
Figure 6-56 : A 24x16 Symbol Example
For creating a new symbol, in addition to write command to CGRAM or DDRAM, note the setting of
the font codes before trying to write characters to be displayed. See the following 2 examples of
creating this 24x16 symbol in DDRAM:
When the first address - (CURX, CURY) of data write to DDRAM is (0, 0), the font code of this symbol are
0x8000, 0x8001 and 0x8002, as Figure 6-57 below:
When the first address of date write to DDRAM is (2, 10h), the font code of this symbol are 0x8105，
0x8106，0x8107 and so on. Please refer the following Program Example(4). The result is show Figure 6-56 on

6-13 Cursor
6-13-1 Cursor Position and Shift
The cursor-moving unit of segment is one byte(or eight pixels). But the moving unit of common is
one pixel. The cursor position is controlled by Register CURX and CURY for both text and graphics
mode. You can also setup the Auto-Increase mode for write to DDRAM or read data from DDRAM.
The cursor-moving boundary depends on the active window.
6-13-2 Full Alignment
The “Full alignment function” provides the “Auto-Align” feature when full-size and half-size
characters combined display. Programmer can adjust it from the settings of Bit-6 of WCCR. (Refer
to register WCCR for detail description.)
Appendix A When Bit-6 is 1, the auto-align feature is enabled.
Appendix B When Bit-6 is 0, the auto-align feature is not being used.
The Figure 6-60 and Figure 6-61 shows the above settings.

The user could control cursor On/Off or Blinking. The register [80h] BTMR is used to set up the
blinking time.
‹
Blinking Time = BTMR[80h] Bit[7:0] x (1/Frame_Rate)
6-13-4 Cursor Width and Height
The cursor height is controlled by register CHWI Bit[7:4], and the height is setting from 1 ~ 16 pixel.
It does depend on user’s requirement.
In normal font, the cursor width fixed to one byte(8 pixels). And cursor’s height is from 1~16pixels
that depends on CHWI Bit[7:4]. In vertical font, the cursor height fixed to 16 pixels, and width is
from 1~8 pixels that depends on CHWI Bit[6:4]. See Figure 6-65 and Figure 6-66 as following.

6-14 Extension Mode for Display
Normally the maximum support resolution of RA8806 is 320x240 dots. But RA8806 support a special
display mode – Extension mode. And the maximum support resolution is 640x240 or 320x480 dots. In
Extension mode, the dual DDRAM data can be show on the bigger panel. This mode is set by the Bit[6:4]
of register MAMR. Please refer to Figure 6-68 of the example by using 640x240 panel, and Figure 6-69
by using 320x480 panel.

Note that the extension mode is only display the combination of the DDRAM1 and DDRAM2 data. The
cursor movement or characters display is not continuous across them. So user must set two pages
separately on the screen. The RA8806 will combine the DDRAM1 and DDRAM2 data as a single display
in extension mode. So, there is some limitation on Extension Mode. For example, if RA8806 set to
Extension Mode(1) as Figure 6-68 for 640x240 dots panel. The data have to write into DDRAM1 and
DDRAM2. But the cursor moving of Common is not from 0 to 639. The users have to separate the
screen into 2 blocks and write data into DDRAM1 and DDRAM2 to create a complete 640x240 dots
picture. The Figure 6-70 shows the description.

6-15 Eliminating Flicker Mode
RA8806 also provides “Eliminating Flicker Mode” in order to eliminate display errors at scan/MPU
confliction. When the scan logic is processing scan task and at the same time the DDRAM is accessed
by the MPU, the scan data will force to get a wrong one and may experience side effects such as
“flicker”. When the flicker is too much, it will infect the display effect.
Therefore, RA8806 is designed to disable scan logic when MPU is accessing the DDRAM. And after it is
completed, the scan logic active again. The “Eliminating Flicker Mode” separate Write and Read
operating therefore no confliction will happen between scan logic and MPU cycle. That is, no data will
lose. Ideally, it will have great improvement at display effect.
In real application, sometimes the cycle time that MPU writes data will be different(font write and
memory clear), although it accesses the RA8806 periodly. On the other hand, the display performance
is still limited when operating under the eliminating-flicker mode in some conditions. The limits are :
(1) The eliminating-flicker mode is suggested to operate under the graphic mode(bit-7 of register[01h]
is setting 1).
(2) Please disable eliminating-flicker function before the memory clear mode. After the memory clear
function is finished, then the eliminating-flicker function could be enable again.

Additionly, RA8806 also supply a method to eliminate flicker by check status. By check the status bit6(SCAN BUSY), user can know whether can access memory that doesn’t conflict the scan data period.

The ideal condition just likes the Figure 6-75. But if the condition likes Figure 6-76, the little part of confliction
that we can not avoid. So if user wants to eliminate the flicker completely by checking SCAN_BUSY, user can
use the method just like the Figure 6-77.

In order to improve the effect of eliminating flicker by check busy, we have two suggestions in real
application :
MPU speed cannot be too slow(The MPU cycle period cannot be too long, just like Figure 6-78),
otherwise the effect of eliminating flicker will be not eminent.
The ITCR value cannot be set too small.(just like Figure 6-79), otherwise the effect of eliminating
flicker will be not eminent.
So if you want to eliminate flicker by check busy of this way, we support a suggestion ITCR setting value
just like Figure 6-80 and Figure 6-81.

Notes:
1. The humidity resistance of the flat package may be reduced if the package is immersed in
solder. Use a soldering technique that does not heat stress the package.
2. If the power supply has a high impedance, a large voltage differential can occur between the
input and supply voltages. Take appropriate care with the power supply and the layout of the
supply lines.
3. All supply voltages are referenced to Gnd = 0V.

When Bit-7 of register “FNCR” is “1”, the contents of ASCII Block Tables 1-4 are show as following Table C5 ~ Table C-8.
Table C-5 shows the standard character encoding of ISO/IEC 8859-1. ISO means International
Organization for Standardization. The ISO 8859-1 also less formally called “Latin-1” is he first eight-bits
coded character sets that developed by the ISO. It refers to ASCII that consisting of 192 characters from the
Latin script in range 0xA0-0xFF. This character encoding is used throughout Western Europe, includes
Albanian, Afrikaans, Breton, Danish, Faroese, Frisian, Galician, German, Greenlandic, Icelandic, Irish,
