Description
(Port A)
8-bit output port. Data is
gated with PPO contents by
OR-gate and they are output.
(8 pins)
(Port B)
8-bit output port. Data is
gated with PPO contents by
OR-gate and they are output.
(8 pins)
Programmable pattern generator (PPG)
output.
Functions as high-precision real-time
pulse output port.
PB0 and PB2 can be 3-state controlled
with PPG.

(Port C)
8-bit I/O port. I/O can be set
in a unit of single bits.
Data is gated with PPO or
RTO contents by OR-gate
and they are output.
(8 pins)
Real-time pulse generator (RTG) output.
Functions as high-precision real-time
pulse output port. PC3 can be 3-state
controlled with RTG. (5 pins)
