ON-Screen Display Controller
MB90097
■ DESCRIPTION
The MB90097 is the on-screen display controller for displaying text and graphics on the TV screen. Since it has
a three-channel output control function, small package, and low voltage requirement for operation, it is suitable
for on-screen display on video equipment such as camera-integrated VTRs.
The MB90097 provides a display screen made up of 28 characters by 12 lines, capable of displaying 512 different
characters each consisting of 12 × 18 dots. The display functions of the MB90097 includes a wealth of character
qualifying functions such as character background shading (shadow casting) and individual character size setting,
supporting 16-color display for each character. They also include the line background, screen background, and
sprite character display functions, enabling the screen to be displayed in a variety of configurations. The integrated
font ROM contains 512 different character patterns all of which can be set by the user.
■ FEATURES

*1: During the horizontal sync signal pulse period, the MB90097 stops its internal operation, disabling writing to
the internal VRAM. Therefore, set the horizontal sync signal pulse width and VRAM write cycle (command 2 or
command 4 issuance cycle) to ensure that: horizontal sync signal pulse width < VRAM write cycle.
*2: Do not change the vertical sync signal (detection edge) in the vicinity of the horizontal sync signal edge of
vertical sync signal detection. Otherwise, it results in a deflection in the display when the sync signal fluctuates.

3. Notes on Issuing Commands
This section summarizes notes on issuing commands.
(1) Initialization
The MB90097 enters the display-off state (*1) upon reset input (input of a LOW-level signal to the RESET pin).
The contents of VRAM (character RAM and line RAM) are not initialized then (undefined immediately after the
power supply is turned on).
When the MB90097 is released from the reset input, issue the following commands to initialize control
operation:
• Dot clock control 1 (Command 11-2)
• I/O pin control (Command 13-0)
After that, set all of other command data and the contents of VRAM.
(VRAM setting requires normal dot clock and sync signal inputs.)
*1: The reset input initializes control bits to 0 as shown below
Screen output control 1A (command 5-00)
SDS = 0
UDS = 0
DSP = 0
I/O pin control (command 13-0)
DCX = 0
DBX = 0
Sprite OFF
Screen background OFF
Character, character background, line
background OFF
Sets the VC0, VC1, VC2, and VC3 pins to
positive logic output.
Sets the BLKA, BLKB, and BLKC pins to positive
logic output.
(2) Command refresh
Command data to the MB90097 and the contents of internal VRAM remain held as long as the MB90097 is
powered. If the serial control, sync, and dot clock signals are affected by external noise, however, they may
become abnormal signals, preventing the internal registers and VRAM from being set normally. You should
therefore refresh all of command data and VRAM data periodically to restore them from the abnormal state.
(3) Command issuance timing
When a VRAM write command, such as a character data setting or line control data setting command, or any
other control command is issued, the command is executed immediately, reflecting the result (command setting)
on the screen. When such a command is issued during a display period, the display in the relevant field may
involve transient distortion. To prevent this, you should issue the command during the vertical blanking interval.
Also, a restriction on the internal circuit configuration may cause deviation of the display position in the first
display field when the DSP, SDS, or UDS control bit of command 5-00 (screen output control 1A) is set from
OFF to ON. To prevent this, you should issue command 5-00 within the 2H period after the leading edge of the
V sync signal.

1. 3 Screen Output Control
The screen output control commands can control three channels of outputs A, B, and C independently.
Their output enable period signals are output to the BLKA, BLKB, and BLKC pins, respectively.
The output-A, -B, and -C control commands can set the character attribute display to OFF, line background
display, and screen background display arbitrarily based on the basic display screen, allowing three independent
screens to be configured and output.
The layer structure of the output screens exists only on the basic display screen. If the output-A, -B, or -C
control command sets the display of an arbitrary area to OFF, the lower layer cannot be displayed but appears
transparent.
The table below shows the relationships between screen output controls and control command bits.

*1: If character display is set to OFF with the character/trimming/character background overlapping the line
background or screen background, the corresponding area of the lower layer is not displayed but appears
transparent.
*2: If line background display is set to OFF with the line background overlapping the screen background, the
corresponding area of the screen background is not displayed but appears transparent.
*3: If sprite display is set to OFF with the sprite character/trimming overlapping a character, character background,
line background, or screen background, the corresponding area of the lower layer is not displayed but appears
transparent.
Note: Three-channel output control for each character serves as output control within the character area. When
trimming dots for a character are displayed in part of the area for an adjacent character, the output of the
trimming dots is controlled by the output control of that adjacent character. If there are trimming dots to the
left of the leftmost character on a line, they cannot be controlled by three-channel output control for each
character. In this case, set a blank character at the left end of the line.
When trimming dots are displayed to the right of the rightmost character on a line, they are controlled with
the three-channel output attribute of the rightmost character.

3. 2 Writing to Display Memory
(1) Writing characters to character RAM
a) Writing a single character
Use the following commands to write data on an arbitrary character to an arbitrary address in character
RAM:
VRAM write address setting
(Command 0)
Character data setting 1
(Command 1)
Character data setting 2
(Command 2)
*1
Set the row and column addresses.
*2
Write the character data to character RAM.
(The VRAM write address is incremented after writing to VRAM.)
*1: When writing to consecutive addresses continuously, you can omit this command for the latter character RAM
write.
*2: You can also omit this command if the current character data is the same as the one set by the preceding
“character data setting 1” command.
Note: Normal writing to VRAM requires input of a normal horizontal sync signal. Input of an invalid horizontal sync
signal may cause VRAM write to fail.
Also, you must set the horizontal sync signal pulse width and VRAM write cycle (command 2 or command
4 issuance cycle) such that: horizontal sync signal pulse width < VRAM write cycle.
b) Writing multiple characters collectively (VRAM fill)
Use the following commands to write data on an arbitrary character to an area of character RAM from an
arbitrary address to the last address, filling the area with that data:
VRAM write address setting
(Command 0)
Character data setting 1
(Command 1)
Character data setting 2
(Command 2)
Set the row and column addresses and specify “VRAM fill”.
The character RAM write executes VRAM fill. * 3
*3: The VRAM fill execution time is about 2 ms for the entire screen.
During execution of VRAM fill, do not issue command 0 to 4.
Issuing command 0 (FL = 0) during execution of VRAM fill will abort the VRAM fill.
(To write to VRAM after VRAM fill has aborted, issue command 0 again to set the VRAM write address.)
Note: Normal execution of VRAM fill requires input of a normal horizontal sync signal. Input of an invalid horizontal
sync signal may cause VRAM fill to fail.
28
MB90097
(2) Writing to line RAM
Use the following commands to write data on an arbitrary line to an arbitrary address in line RAM:
*4
VRAM write address setting
(Command 0)
Line control data setting 1
(Command 3)
Line control data setting 2
(Command 4)
Set the row address.
*5
Write the line data to line RAM.
(The VRAM write address remains unchanged.)
*4: The line RAM fill function is not available. (It is prohibited to specify “Line RAM fill”.)
*5: You can omit this command if the current line control data is the same as the one set by the preceding “line
control data setting 1” command.
Note: Normal writing to VRAM requires input of a normal horizontal sync signal. Input of an invalid horizontal sync
signal may cause VRAM write to fail.
Also, you must set the horizontal sync signal pulse width and VRAM write cycle (command 2 or command
4 issuance cycle) such that: horizontal sync signal pulse width < VRAM write cycle.

• Trimming color (Setting for each line, selected from among 16 colors)
Line control data setting 1 (Command 1): Bits LF3 to LF0
(4) Trimming display rules
The following display rules apply to trimming display:
• Trimming dots for a character can be displayed in the right or left adjacent character area only when the
character background types of the two characters are the same.
• Trimming dots for the character at the left or right end of a line can be displayed beyond the character area
only when the character background type is “no character background”.
(When three-channel output control for each character is used, however, do not attempt to display trimming
dots outside the character area at the left end of a line. Trimming dots for that area cannot be controlled in
character units. Note also that trimming dot display outside the character area at the right end of a line
depends on the character output control setting for the rightmost character on the line.)
• Trimming display for a character does not apply to the areas above and below the character (the area for the
character on the line above, the area for the character on the line below, the upper line spacing, and the lower
line spacing).
• When a line is displayed enlarged, trimming dots on the line are not enlarged but those in the normal dot
size are displayed around the enlarged character dots.
Note: For output control of each character using three-channel output control, design the display and font taking
account of trimming dot display protruding to the area for the adjacent character to the right or left.
Three-channel output control for each character is display output control of the character area. Turning on
or off the display of trimming dots protruding to the right or left adjacent character area depends on the
character output control setting for that adjacent character.

MB90097
4. 3 Line Enlarged Display
Line enlarged display control is used to control the display size of each line including the characters, character
backgrounds, and line background on that line (as well as the line spacing portions). This also controls
enlargement of the shadow frames of shaded backgrounds. It does not however control the enlargement of the
trimming dot width.
Note that the lines and characters following the line for which line enlarged display has been specified are shifted
down accordingly.

■ CONTROL FUNCTIONS
1. Serial Command Control
The MB90097 executes serial command/data transfer using the chip select (CS), serial clock (SCLK), and serial
data input (SIN) pins. The data transfer direction (MSB-first or LSB-first transfer) is selected under control of the
serial data input direction select (SDR) pin. The data length is 16 bits. If the CS pin goes HIGH during transfer
with data less than 16 bits, command transfer is not guaranteed. Keeping the CS pin LOW allows multiple items
of command data to be transferred continuously. (It is however recommended to set the CS pin to the HIGH
level at intervals of tens of words for word synchronization.)
The SCLK clock frequency is 4 MHz at maximum. Set it such that: VRAM write cycle (a minimum of 16 clock
pulses) > input horizontal sync pulse width. If this condition is not satisfied, VRAM write may fail.)

3. Sync Signal Input
3. 1 Vertical Synchronization Detection
Vertical synchronization is detected by sensing the level of the vertical sync signal at the leading or trailing edge
of the horizontal sync pulse to detect the transition. The vertical display position on the screen depends on the
vertical synchronization detection position.
Use I/O pin control (command 13-0) to select operation control.

3. 2 Operation in Horizontal Synchronization
(1) Operation with dot clock LC oscillation
The sync pulse of the input horizontal sync signal is used to control the oscillation and stop of the dot clock,
enabling display horizontal synchronization.
Bit HE (horizontal synchronization operation edge) of I/O pin control (command 13-0) must be set to “0”.

3. 3 Vertical Blanking Control
Vertical blanking control is used to internally generate the vertical blanking interval for display signal output
control.
Display singnal output is stopped during the vertical blanking interval.
Vertical blanking control results in either of the following two operations depending on the setting of bit VVE
(vertical synchronization detection edge selection control) of I/O pin control (command 13-0).
(1) Operation of vertical sync leading-edge detection

3. 4 Horizontal Blanking Control
Horizontal blanking control is used to generate the horizontal blanking interval for display signal output control.
Display signal output is stopped during the horizontal blanking interval.
Horizontal blanking control can be set for the back porch or front porch by command control.
Horizontal blanking control results in either of the following two operations depending on the setting of bit HE
(horizontal synchronization operation edge selection control) of I/O pin control (command 13-0).
(1) When the horizontal synchronization operation edge is the trailing edge (bit HE = 0)

Setting between 0 and 126 dots in 2-dot units.
• Horizontal blanking (front porch) control
Horizontal blanking control 2 (Command 13-2): Bits BF8 to BF0
Setting between 0 and 1022 dots in 2-dot units.
Notes: 1. The back porch must be shorter than the front porch. Do not make any other setting.
2. The actual horizontal blanking interval is offset from the set value by several tens of dots in the positive
direction.

• If character display of a character is turned OFF by bits OA2-OA0, OB2-OB0, OC2-OC0, or MO1, MO0, the
character (including its trimming and character background) is displayed transparent, including the
corresponding portion of the lower layer (line and screen backgrounds).
• If line background display is turned OFF by bit BLB, the line background and the corresponding portion of the
screen background display layer are displayed transparent.
• If line background display is turned OFF by bit BLC, the line background and the corresponding portion of the
screen background display layer are displayed transparent.
• If screen background display is turned OFF by bit BGB, the screen background display layer is displayed
transparent.
• If screen background display is turned OFF by bit BGC, the screen background display layer is displayed
transparent.
• If sprite character display is turned OFF by bit SCB, the sprite character (including its trimming) and the
corresponding portions of all lower layers are displayed transparent.
• If sprite character display is turned OFF by bit SCC, the sprite character (including its trimming) and the
corresponding portions of all lower layers are displayed transparent.

MB90097
(2) Output-A/B/C control
The character attributes (character, trimming, and character background) of each character can be displayed
by three-channel (A/B/C) output control.
Commands 5-00 to 5-02 are used for output control for each screen; command 2 is used for output control for
each character.
When trimming dots for a character are displayed protruding to the area for an adjacent character, the output
of the trimming dots is controlled by the character output control of that adjacent character. Three-channel output
control for each character serves as output control within the character area (12 × 18 dots for normal-sized
characters).
If there are trimming dots to the left of the leftmost character on a line, they cannot be controlled by three-channel
output control. In this case, place a blank character at the left end of the line and set characters to be displayed
to the right.
When trimming dots are displayed to the right of the rightmost character on a line, the three-channel output
control of the trimming dots depends on the character output control of the rightmost character.
• Output-A character control
Screen output control 1A (Command 5-00):Bits OA2 to OA0
Settable, selected from among eight types.
• Output-B character control
Screen output control 1B (Command 5-01): Bits OB2 to OB0
Settable, selected from among eight types.
• Output-C character control
Screen output control 1C (Command 5-02): Bits OC2 to OC0
Settable, selected from among eight types.
• Character output control
Character data setting 2 (Command 2): Bits MO1 and MO0
Settable, selected from among four types for each character.
