Command Descriptions
Note: 1. After a hardware reset, always first send register 00 command, and only then issue the various commands. The
LC78711E may operate incorrectly if a register 00 command is not issued.
Note:
2. All data transfers must be performed LSB first.
Note:
3. The (0) and (1) notations in the second byte indicate the default values.
1. Register 00hex
Data7: INIT
— Function: System reset
— Operation: INIT = 0: The LC78711E internal state is not reset (normal operation continues)
INIT = 1: The internal state is reset (The display is set to a blue background screen.)
Data6: SCP2
Data5: SCP1
Data4: SCP0
— Function: YS output (pin 46) control
— Operation: SCP2 = 0: When (SCP0, SCP1) is (0,0) or (0,1), the whole screen is set to low (transparent) if the
comparison condition did not hold.
SCP2 = 1: When (SCP0, SCP1) is (0,0) or (0,1), the whole screen is set to high (display) if the
comparison condition did not hold.
The superimpose mode comparison condition is determined by the SCP1 and SCP2 setting.
(Only valid when pin 60, SON, is 1)
Data3: CB
— Function: Color bar screen output setting
— Operation: CB = 0: The graphics signal is output.
CB = 1: A color bar signal is output.
Data2: 1
— Operation: This bit must always be set to 1. The LC78711E may not operate correctly if this bit is not set to 1.
Data1: 0
— Operation: This bit must always be set to 0. The LC78711E may not operate correctly if this bit is not set to 0.
Data0: VRAM/BG
— Function: Switches the displayed screen
— Operation: VRAM/BG = 0: Displays the contents of VRAM
VRAM/BG = 1: Displays the background color
No. 5476-20/43
LC78711E
SCP1

Comparison condition (YS pin output operation setting)
0
0
No comparison performed
1

If the border color was not black, YS is set to high (display) for sections that do not match
the border color, and set to low (transparent) for all other sections.
1
1
Sets YS high for sections that do not match the chroma key color, and low for all other
sections.
