Analog power supply
I/O power supply for external interface.
Chip selection
In M68 mode, this is used to select operation, read or write (RWB).
In I80 mode, this serves as a read strobe signal (RDB).
The signal for register index or register command select.
Low: Register index or internal status (in read operation)
High: Register command.
In M68 mode, this serves as a write/read enable strobe (E).
In I80 mode, this serves as a write strobe signal (WRB).
Frame synchronizing signal
Horizontal Line synchronizing signal
Dot clock signal
A data ENABLE signal in the RGB I/F mode
Serial data transfer output in the serial data transfer interface mode
Serial data transfer input/output in the serial data transfer interface mode
In SPI mode, this serves as a synchronous clock (SCL)
Reset pin. Setting this pin to low initializes the LSI. Must be reset after power is
supplied
Data bus for SYSTEM I/F
Data bus for RGB I/F
Connected unused pins to the IOVCI or VSS level
Mode selection pin for Serial Peripheral Interface.
If SPI3 = 0, 4-wire SPI mode
If SPI3 = 1, 3-wire SPI mode. That is, SDI is bidirectional pin.
6-bit interface, 3-transfer
16-bit interface, 1-transfer
18-bit interface, 1-transfer
