22. General-purpose output ports; Pin 37: CONT1, pin 74: CONT2
The CONT1 and CONT2 pins can be set to high or low by commands from the control microprocessor.
Note that the CONT1 reset command also resets the CD-ROM XA mode, and thus care is required when using this
command.
23. General-purpose I/O ports; Pin 38: P0/DFCK, pin 39: P1/DFIN, pin 40: P2, pin 41: P3/DFLR, pin 18: P4, pin 33: P5
The LC78631E provides six I/O ports: pins P0 to P5. These pins all function as input pins after a reset. Unused ports
must be connected to ground or set to output mode.
The port information can be read from the SQOUT pin in the order P0 to P5 in synchronization with CQCK falling
edges by issuing the port read command. Note that data can be read out in the same manner when another command
is issued.
These ports can be set independently to be control output pins by the two-byte port I/O set command. Ports are
selected with the lower 6 bits of the data byte.
dn = 1 .................Sets port Pn to be an output pin.
dn = 0 .................Sets port Pn to be an input pin.
n = 0 to 5
