General Description
The EM65571 is one of the industry’s most advanced wide-screen STN-LCD drivers for
65K-color displays. It has a built-in display RAM, a power supply circuit for LCD drive,
an LCD controller circuit, and support for LCD cell tolerance compensation of VLCD by
external pin selection. It also supports the EEPROM function for programming
information to tune VLCD offset voltage to get the best contrast. Therefore, this
contributes to a compact system design. In addition, its partial display function realizes
low power consumption.
*Partial display function: A function that utilizes only part of the screen, thus reducing
power consumption.

7.1.5 Serial Interface
The EM65571 has two types of serial interface.
One is a 3-wire type serial
interface; the other one is a 4-wire type serial interface. The choice whether 3-wire
or 4-wire is determined by the SMODE pin.
SMODE = “L”: 4-wires serial interface
SMODE = “H”: 3-wires serial interface
7.1.6 4-wire Serial Interface
When chip select is active (CSB = “L”), 4-wire type serial interface can work
through the SDA and SCL input pins. When chip select is inactive (CSB = “H”), the
internal shift register and counter are reset to the initial condition. Serial data SDA
is input sequentially in the order from D7 to D0 at the rising edge of the serial clock
(SCL) and is converted into 8-bit parallel data (by serial to parallel conversion) at
the rising edge of the 8th serial clock, processed in accordance with the data. The
identification whether serial data input (SDA), display data or control register data
is determined by input to the RS pin.
RS = “L” : display RAM data
RS = “H” : control register data

After completion of an 8-bit data transfer, or when making no access, be sure to set
the serial clock input (SCL) to “L”. Care of the SDA and SCL signals against
external noise should be taken into consideration during board wiring. To prevent

7.3 Internal Register Read
In the case of display RAM read operation, you need to perform a dummy read one
time. The designated address data is not output to read operation immediately
after the address is set to AX or AY register, but is output when the second data is
read. Dummy read is always required one time after an address set and write
cycle.

EM65571
130COM/128SEG 65K Color STN LCD Driver
The EM65571 can read the control registers, in case of control register read
operation, the data bus upper nibble (D7-D4) is used for register address (0 to FH).
A maximum of 16 registers can be accessed directly. Since there are more than 16
registers, the EM65571 has a register bank control. The RE register sets the bank
number to be accessed. And the RE address is 0FH, in any bank that can access
RE register, 4-steps are needed to read a specific register.
1. Write 04H to the RE register to access the RA register.
2. Write the specific register address to the RA register.
3. Write specific register bank to RE register.
4. Read specific register contents.

7.4 16-Bit Data Access to Display RAM
The EM65571 corresponds to 8-bit and 16-bit bus size access.
The data bus size can be selected by the WLS register.
WLS = “0”: 8-bit bus size
WLS = “1”: 16-bit bus size
In the 16-bit access mode, in accessing the control register, use the low-byte data bus
(D7~D0). High byte data bus (D15~D8) are not used in internal circuits when reading
the control register using 16-bit bus. Register values are output to D3-D0 and D15-D4
output “H”.
7.5 Fast Burst RAM Write Function
The EM65571 has a built-in fast burst RAM write function. The burst mode transfers 32
bits of data in a block at once, so it can decrease half the access time needed for
common standard RAM write functions (16 bits data bus). The burst RAM write
function is suitable for frequently rewriting data such as displaying color animation.

7.6 Display Start Address Register
This register determines the Y-address of the display RAM corresponding to the
display start line. The display RAM data addressed by the Display Start Address
register is output to the common driver start line. The actual common start line of the
LCD panel depends on the Display Start Common register and the SHIFT bit of the
Display Control register. The registers are preset every time the FLM signal varies in
the display line counter. The line counter counts up when synchronized with the LP
input and generates line addresses which are read out sequentially as 384 bits of data
from display RAM to the LCD driver circuit.
7.7 Display RAM Addressing
The EM65571 has a built-in bit mapped display RAM. The display RAM consists of
2048 bits (16 bits*128) in the X-direction and 128 bits in the Y-direction. In the
gradation display mode, the EM65571 provides segment driver output for 48-gradation
display using 6 bits. The three outputs of the segment driver can be used for one pixel
of RGB. When connected to an STN color LCD panel, the EM65571 can display
128*128 pixels with 65K colors (48 gradation * 48 gradation * 48 gradation). The
address area in the X-direction depends on the access bus size. In the X-direction, the
X Address register is used to access; and in the Y-direction, the Y Address register is

The addresses, X-address and Y-address can be set up so that they can increment
automatically with the address control register. The increment is made every time the
display RAM is read from or written to in the MPU. In the Y-direction, 384 bits of data
are read out to the display data latch circuit by internal operation when the LP rises in a
one-line cycle. They are output from the display data latch circuit when the internal
signal LP fails. When internal FLM signals output in one frame cycle are at “H”, the
values in the display start line register are preset in the line counter and the line counter
counts up at the falling edge of the internal signal LP. The display line address counter
is synchronized with each timing signal of the LCD system to operate and is
independent of the address counters X and Y.
7.8 Display RAM Access Using Windows Function
The EM65571 has a window area setting command for specified display RAM area
access. To use the window function, you need to set up two positions X and Y
addresses. You also need to set up the auto increment mode (AXI=”1”, AYI=”1”). Two
position means window start position and window end position. The window start
position’s X and Y-address set to normal the X-address (AX) and Y-address (AY)

registers. The window end position’s X and Y address set to Window the X-end
Address (EX) and Window Y-end Address (EY) register. In window function access,
you can modify the write access and set to AIM=”1”. In the case of using window
function access, it should be set to the following registers before accessing the RAM.
WIN = “1”, AXI=”1”, AYI=”1”
X-Address, Y-Address, Window X-end Address, Window Y-end Address
Moreover, you should keep the following address conditions:
Window end X-address (EX) ≧ Window start X-address (AX)
Window end Y-address (EY) ≧ Window start Y-address (AY)

7.9 Display RAM Data and LCD
One bit of display RAM data corresponds to one dot of LCD. Normal display and
reverse display by REV register are setup as follows.
Normal display (REV=0): RAM data = “0” not lighted
RAM data = “1” lighted
Reverse display (REV=1): RAM data = “0” lighted
RAM data = “1” not lighted
7.10 Segment Display Output Order/Reverse Set up
The order of display output, SEGA0, SEGB0, SEGC0 to SEGA127, SEGB127, and
SEGC127 can be reversed. If REF control bit is set to “1”, display by reversing access
to display the RAM from the MPU by using REF register. This reduces the limitation in
placing IC when assembling an LCD panel module.

Figure 11. Display RAM Block Diagram
The EM65571 executes address conversion that depends on the control register
setting. In case of auto increment mode, usually the AX register is incremented by one.
For instance when REF and AXI are both “1”, the AX register is incremented by one,
but the effective X-address seems to decrement because of address conversion. The
effective Y-address use AY register values as it is.

EM65571
130COM/128SEG 65K Color STN LCD Driver
7.12 Display Data Structure and Gradation Control
For the purpose of gradation control, one pixel requires multiple bits of display RAM.
The EM65571 has 5-bit of data per output to achieve the gradation display.
The three outputs of the segment driver are used for one pixel of RGB, and the
EM65571 is connected to an STN color LCD panel. It can display 128*128 pixels with
65K colors (5 bits * 6 bits [5+FRC] * 5 bits). In this case, since the gradation display
data is processed by a single access to the memory, the data can be rewritten fast and
naturally.
The weighting for each data bit is dependent on the status of the SWAP bit and the REF
bit that is selected when data is written to the display RAM.

Gradation LSB Control
In 256 color mode (C256=1), the EM65571 provides segment driver output for
8-gradation display using 3 bits and for 4-gradation display using 2 bits.
The segment driver output for the 4-gradation display uses 2 bits written to the
corresponding RAM area and 1 bit supplemented by the gradation LSB circuit, and
then selects 4-gradation from 8-gradation.
In 256 color mode (C256=1), the segment driver output for the 4-gradation display
results in a gradation level of 0 regardless of the gradation LSB when 2 bits of data on
the display RAM are “00”. When 2-bits of data on the display RAM are “11”, a gradation
level of 7/7 is selected regardless of the bit information of the gradation LSB. The other
gradation levels are selected depending on the 2 bits of data on the display RAM and
the gradation LSB bits.
One bit of data is supplemented by setting the gradation LSB register (GLSB).
The Gradation LSB control bit is applied to all 4-gradation segment drivers.
Gradation LSB = “0”: Select 0 as the LSB information on the RAM for 4-gradation
segment drivers.
Gradation LSB = “1”: Select 1 as the LSB information on the RAM for 4-gradation
segment drivers.

The EM65571 has two gradation display modes, the gradation fixed display mode and
the gradation variable display mode. Select either of the two modes using the
gradation display mode register.
PWM = “0”: Select the variable display mode using 32 gradations selected from 48
gradations (65K=1, C256=0).
Select the variable display mode using 16 gradations selected from 48
gradations (65K=0, C256=0).
Select the variable display mode using 8 gradations selected from 48
gradations (65K=0, C256=1).
PWM = “1”: Select the fixed display mode using specific 32 gradations
(65K=1, C256=0)
Select the fixed display mode using specific 16 gradations
(65K=0,C256=0)
Select the fixed display mode using specific 8 gradations
(65K=0,C256=1)
To select the best gradation level suited for the LCD panel, use the gradation palette
register among the 48-level gradation palettes in the gradation variable display mode.
The segment driver output is set up by the selected 32-levels of gradation palettes.
The gradation palette register provides three registers for the SEGAi (0-127) group,
SEGBi (0-127) group, and SEGCi (0-127) group of segment driver outputs [palettes Aj,
Bj, and Cj (j = 0-31)]. Each register consists of a 6-bit register, selecting 32 gradations
from the pattern for 48 gradations.

EM65571
130COM/128SEG 65K Color STN LCD Driver
7.16
Display Timing Circuit
The display timing circuit generates internal signals and timing pulses (internal LP, FLM, M)
by clock. It can select external input (CK) or internal oscillation.
Symbol
LP (internal)
LP or latched clock signal. At the rising edge, count the display line counter.
At the falling edge, output the LCD drive signal.
FLM (internal)
FLM or First Line Maker, signal for LCD display synchronous signals. When
FLM is set to “H”, the display start-line address is present.
M (internal)
7.17
Description
Signal for LCD drive output alternated signals.
Signal Generation to Display Line Counter and Display Data
Latching Circuit
Both the clock for the line counter and the clock to display the data latching circuit from the
display clock (internal LP) are generated. Synchronized with the display clock (internal LP),
the line addresses of the Display RAM are generated and 384-bit display data are latched
to display the data latching circuit and output to the LCD drive circuit (segment output).
Read-out of the display data to the LCD drive circuit is completely independent of the MPU.
7.18
Generation of the Alternated Signal (internal M) and the
Synchronous Signal (internal FLM)
The LCD alternated signal (internal M) and synchronous signal (internal FLM) are
generated by the display clock (internal LP). The FLM generates an alternated drive
waveform to the LCD drive circuit. Normally, the FLM generates alternated drive waveform
every frame (M-signal level is reversed every one frame). However, by setting up data
(n-1) in an n-line reverse register and n-line alternated control bit (NLIN) at “1”, an n-line
reverse waveform is generated.
7.19
Display Data Latching Circuit
The display data latching circuit temporally latches the display data that is output to the
LCD driver circuit from the display RAM, once every one common period. Normal
display/reverse display, display ON/OFF, and display all on functions are operated by
controlling the data in the display data latch, therefore, no data within the display RAM
changes.

LCD Driver Circuit
This driver circuit generates four levels of LCD driver voltage. The circuit has 384-segment
output and 130-common output and outputs a combined display data and internal signal M.
Two of the common outputs, COMA and COMB, are special outputs. The COMA and
COMB outputs are not influenced by partial setting, they are mainly used for display. The
common driver circuit that has shift register sequentially outputs common scan signals.

7.22
Oscillator Circuit
The EM65571 has a CR oscillator. The output from this oscillator is used as the timing
signal source of the display and the boosting clock for the booster.
When external clock is used, feed the clock to CK pin.
The duty cycle of the external clock must be 50%.
The resistance ratio of the CR oscillator is programmable. If you change this ratio, also
change the frame frequency for display.
7.23
Power Supply Circuit
This circuit supplies voltages necessary to drive an LCD. The circuit consists of a booster
and a voltage converter.
Boosted voltage from the booster is fed to the voltage converter that converts this input
voltage into V0, V1, V2, V3 and V4 that are used to drive the LCD. This internal power
supply should not be used to drive a large LCD panel containing many pixels. Otherwise,
the display quality will degrade considerably. Instead, use an external power supply.
When using an external power supply, turn off the internal power supply (AMPON,
DCON=”00”), disconnect pins CAP1-, CAP1+, CAP2+, CAP2-, CAP3+, CAP4+, CAP5+,
CAP6+, VOUT and VEE. Then, feed the external LCD drive voltages to pins V0, V1, V2, V3
and V4. The power circuit can be controlled by a power circuit related register. So, partial
function of the built-in power circuit can be used with external power supply.

Booster Circuit
Placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-, across CAP3+
and CAP1-, across CAP4+ and CAP2-, across CAP5+ and CAP1-, across CAP6+ and
CAP2-, and across VOUT and VSS will boost the voltage coming from VEE and VSS nth
times and outputs the boosted voltage to the VOUT pin. The boosted voltage, either twice,
three times, four times or five times the supply voltage and which is output to the VOUT pin
is determined by the boost step register, and set by a command instruction.
—
In case the required voltage is twice the voltage supply, this is achieve by placing
capacitor C1 only across CAP1+ and CAP1-, and opening CAP2+, CAP2-,
CAP3+, CAP1-, CAP4+, CAP2-, CAP5+, CAP1-, CAP6+ and CAP2-.
—
In case the required voltage is three times the voltage supply, this is achieve by
placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-, and
opening CAP3+, CAP1-, CAP4+, CAP2-, CAP5+, CAP1-, CAP6+ and CAP2-.
—
In case the required voltage is four times the voltage supply, this is achieve by
placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-,
across CAP3+ and CAP1-, and opening CAP4+, CAP2-, CAP5+, CAP1-, CAP6+
and CAP2-.
—
In case the required voltage is five times the voltage supply, this is achieve by
placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-,
across CAP3+ and CAP1-, across CAP4+ and CAP2-, and opening CAP5+,
CAP1-, CAP6+ and CAP2-.
—
In case the required voltage is six times the voltage supply, this is achieve by
placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-,
across CAP3+ and CAP1-, across CAP4+ and CAP2-, across CAP5+ and CAP1-,
and opening CAP6+ and CAP2-.
—
In case the required voltage is seven times the voltage supply, this is achieve by
placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-,
across CAP3+ and CAP1-, across CAP4+ and CAP2-, across CAP5+ and CAP1-,
across CAP6+ and CAP2-.
When using a built-in booster circuit, the output voltage (VOUT) must be less than the
recommended operating voltage (20V). If the output voltage (VOUT) is over the
recommended operating voltage, the proper and full functionality of the chip cannot be
guaranteed.

When using 7x boosting ratio, the VEE operating voltage should not exceed 2.8V. For a
guaranteed result, the VOUT should be less than the recommended operating voltage of
20V.
7.25
Electronic Volume
The voltage conversion circuit has a built-in electronic volume, which allows the VBA to be
controlled with DV register setting. The DV registers are 7 bits, so it’s advisable to select
113 voltage values for the VBA voltage. The relationship between VBA and DV is shown in
the following equation:
⎡ M + Offset ⎤
VBA = ⎢1 +
⎥⎦ × VREF
381
⎣
where
M: DV register value (8~20)
Offset: CV1~CV4 setting
VREF: Internal temperature compensation output voltage
7.26
Voltage Regulator
The EM65571 has a built-in reference voltage regulator, which generates the voltage
amplified by the input voltage from the internal temperature compensation output voltage
VREF pin. The generated voltage is output at the V0 pin. Even if the boosted voltage level
fluctuates, V0 remains stable as long as VOUT is higher than V0. Stable power supply can
be obtained using this constant voltage, even if the load fluctuates. The EM65571 uses the
generated V0 level for the reference level of the electronic volume to generate an LCD
driver voltage.
7.27
Voltage Generator Circuit
The voltage converter contains the voltage generator circuit. The LCD driver voltages other
than V0, which is, V1, V2, V3 and V4 are obtained by dividing V0 through a resistor
network. The LCD driver voltage from EM65571 is biased at 1/5, 1/6, 1/7, 1/8, 1/9, 1/10,
1/11, 1/12 or 1/13. When using the internal power supply, connect a stabilizing capacitor
C2 to each of the pins V0 to V4. The capacitance of C2 should be determined while
observing the LCD panel to be used. When using an external power supply, apply external
LCD driver voltages to V0, V1, V2, V3, V4, and disconnect pins CAP1+, CAP1-, CAP2+,
CAP2-, CAP3+, CAP4+, CAP5+, CAP6+, VOUT, VEE. When using only the voltage
conversion circuit, turn off the internal booster circuit, disconnect pins CAP1+, CAP1-,
CAP2+, CAP2-, CAP3+, CAP4+, CAP5+, CAP6+ and VEE. Derive the voltage source to
be supplied to the voltage converter from the VOUT pin.

EEPROM Function
For the EM65571 to support EEPROM function to tune to the LCD operating voltage Vop,
first, select EEPROM operating mode, EEPROM power from internal or external, and initial
oscillator frequency or faster oscillator frequency (+50%). Select the register (Bank5 [AH]),
using (M1, M0) to select the operating mode for the EEPROM, (M1, M0) = 00 → Read
information from the EEPROM; (M1, M0) = 01 → Program information to the EEPROM;
(M1, M0) = 10 → Erase information on the EEPROM; (M1, M0) = 11 → Reserved.

Secondly, the power supply for the EEPROM is selective. By setting the VPP_EXT control
bit of the register, you can select internal power (from V0) or external power to support the
EEPROM. VPP_EXT=0 → internal power; VPP_EXT=1 → force 16~18V from the VPP
pin externally.
Thirdly, you can select the oscillator frequency by setting the OSC control bit of register.
OSC=0 → initial oscillator frequency setting; OSC=1 → oscillator frequency + 50%.
You can get Vop calibration offset voltage by setting the Vop calibration offset register.

Precautionary Measures during Power ON and Power OFF
High current that may flow if a voltage is supplied to the LCD driver power supply while the
system power supply is floating may permanently damage this LSI. The details are as
follows.
7.32.1 When Using an External Power Supply
—
Procedure for Power ON
o Logic system (VDD) power ON, make reset operation.
o Supply external LCD driver voltage to corresponding pins (V0, V1, V2, V3 and V4)
—
Procedure for Power OFF
o Set HALT register to “1” or initiate a reset operation.
o Cut off external LCD driver voltage.
o Logic system (VDD) power OFF.
Note: Connect a serial resistor (50 to 100Ω) or fuse to the LCD driver power V0 or VOUT
(when using only an internal voltage conversion circuit) of the system as a current
limiter. Moreover, set up suitable resistor values corresponding to the LCD display
grade.
7.32.2
—
When Using a Built-in Power Supply
Procedure for Power ON
o Logic system (VDD) power ON
o Booster circuit system (VEE) power ON
o Initiate a reset operation, enable booster and voltage conversion circuit.
If the VDD and VEE voltages are not of the same potential, turn on the power logic system
(VDD) first.

o Set the HALT register to “1” or reset the system.
o Booster circuit system (VEE) power OFF.
o Logic system (VDD) power OFF.
If VDD and VEE are not of the same potential, turn off the VEE first. After VEE, VOUT, V0,
V1, V2, V3 and V4 voltages are below LCD ON voltage (threshold voltage for Liquid crystal
turn on), power off the logic system (VDD).

8.2 Control Register Functions
The EM65571 has many control registers. In case of control register access, the upper
nibble of the data bus (D7~D4) represents the register address, the lower nibble of the
data bus (D3~D0) represents the data. The access example is shown in the following.
The Pins (CSB, RS, RDB, WRB) setting is for the 80-family MPU interface. Only the
setting of the terminal (RDB, WRB) is different, when it is accessed by the 68-family
MPU.

Register Bank
In writing to the control register, direct addressing to D7~D4 of the data bus can be
used. In case of a register read, first set the RA register for a specific register address,
next read that specific register. Therefore, two steps are needed to perform a register
read. Then, specific register output to D3~D0 of the data bus. Except for D3~D0 of the
data bus, all are “H”. Access to undefined register address area is not allowed. When
RS is “L”, all read/write operations are accessible in the display RAM. The data bus
does not include the register address. In case of a write operation, D3~D0 data is
written to the register designated at D7~D4 at the rising edge of the WRB signal. In

This register controls the increment mode and window function when accessing the display
RAM. The increment operation of AX and AY registers can be controlled by AIM, AYI and
AXI registers setting and every write access or every read access to the display RAM. The
AY register directly connects to the display RAM as Y address. The AX register connects to
the address converter, and outputs to the display RAM as X address in the auto-increment
mode, the AX and AY register are then incremented, but not directly increment the X and Y
addresses.
In setting the control register, the address increment operation can be made without setting
successive addresses for writing data to the display RAM or reading data from the MPU.
The WIN register is used for window function control.
WIN=”0”: Normal RAM access
WIN=”1”: Window function access
In the case of accessing the window function, the following register should be set before
accessing the RAM.
WIN=”1”, AXI=”1”, AYI=”1”
X-address, Y-address, Window X End Address, Window Y End Address
Moreover, the following address condition should be kept:
Window end X address ≧ Window start X address
Window end Y address ≧ Window start Y address
Refer to “6-7 Display RAM access using Window Function” for details on window function.

ACL
The internal circuit can be initialized.
ACL = “0”: Normal operation
ACL = “1”: Initialization ON
When a reset operation begins internally after the ACL register is set to “1”, the
ACL register is automatically cleared to “0”. An internal reset signal is generated
by a clock (built-in oscillation circuit or CK input) for the display. Hence, include a
WAIT period for the display clock for at least two cycles. After a WAIT period,
proceed with the next operation.
—
DCON
The internal booster circuit is set ON/OFF
DCON = “0”: Booster circuit OFF
DCON=”1”: Booster circuit ON
—
HALT
The conditions of power saving are set ON/OFF by this command.
HALT = “0”: Normal operation
HALT=”1”: Power-saving operation
When setting in the power-saving state, the consumed current can be reduced to
a value near to the standby current.
The internal conditions at power saving are as follows.
a. The oscillating circuit and power supply circuit are stopped.
b. The LCD driver is stopped, and output of the segment driver and common driver
are VSS level.
c. The clock input from the CK pin is inhibited.
d. The contents of the Display RAM data are maintained.
e. The operational mode maintains the state of command execution before
executing power saving command.

In order to prevent a transient voltage from being generated when an electronic volume
code is set, the circuit is designed in such a way that the set value is not reflected
immediately as a level but only after the upper bits (DV6-DV4) of the electronic code have
been set. The set value becomes valid when the lower bits (DV3-DV0) of the electronic
control volume code have also been set.

Relationship between Setting and Common/Display RAM
The relationship between the COM pin numbers and the addresses in the Y-direction
on the display RAM changes according to the SHIFT command, LCD Duty Set
command, Display Starting Common Position Set command, and Display Starting Line
Set command.
When “0” is selected for the display starting line:
The relationship between the COM pin and the addresses in the vertical direction of the
display RAM (hereafter called MY) changes on a 15-dot basis according to the LCD
Duty Set command and the Display Starting Common Position Set command. The
common positions change in the forward direction when the SHIFT bit is “0”, and
change in the reverse direction when the SHIFT bit is “1”. When “0” is selected as the
value for LA7 to LA0 in the Display Starting Line Set command, the MY number
corresponding to the display starting position is “0”. The MY numbers are sequentially
shifted backward when display occurs. In any case, the relations of COMA = MY160
and COMB = MY161 do not change.
When non-zero is selected for the display starting line:
The relationship between the COM pins and the addresses in the vertical direction on
the display RAM MY changes on a 15-dot basis according to the information in the LCD
Duty Set command and Display Starting Common Position Set command. The
common positions change in the forward direction when the SHIFT bit is “0”, and
change in the reverse direction when the SHIFT bit is “1”. If non-zero is selected for the
values for LA7 to LA0 in the Display Starting Line set command. The MY number
corresponding to the display starting position shifts with the set value. The MY number
shifts backward when display occurs. If it exceeds 159, it returns to 0, and then shifts
sequentially. In any case, the relations of COMA = MY160 and COMB = MY161 do not
change.
When you want a mirror image in the Y-direction like the following figure, you must set
additional commands to complete this operation:
WRITE 0xF0
WRITE 0x8D
WRITE 0x22
WRITE 0xF4
WRITE 0x63
//bank 0
//shift=1 ; 65k color ; display on
//Y address=2
