Serial Input/Output Pin
Under the Serial Data Transfer Mode, this pin functions as an I/O
Pin.
Under the Parallel Data Transfer Mode, this pin may be connected
to either “H” or “L”
Parallel Data Input/Output Pins
Under the Parallel Data Transfer Mode, these pins are used as I/O
Pin.
Under the 4-bit Transfer Mode, DB4 to DB7 are used.
I/F Select Pin
This pin is used to select the I/F mode: Serial or Parallel Transfer
0: Serial Data Transfer
Interface Select Pin
This pin is used to select the interface mode: i80 or M68.
0: i80 CPU Mode
Chip Select Pin
When this pin is set to “L” the PT6314 is active.
Segment Output Select Pin
This pins are used to set SG1 to SG80.
Extension Grid Driver Clear Signal Output Pin
Active: Low
The Grid Data stored in extension driver latch are outputted
when this pin is set to “HIGH”. If this pin is set to ”LOW”, the
extension driver outputs LOW.
