CXP88452/88460

Pin 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)

(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)

(Port D)

8-bit I/O port. I/O can be

set in a unit of single bits.

(8 pins)

(Port E)

8-bit port. Bits 2, 3, 4 and 5

are for inputs; bits 0, 1, 6

and 7 are for outputs.

(8 pins)

Programmable pattern generator (PPG)

output. Functions as high precision real-

time pulse output port.

(19 pins)

PB0 and PB2 can be tri-state controlled

with PPG.

Real-time pulse generator (RTG) output.

Functions as high precision real-time

pulse output port. PC3 can be tri-state

controlled with RTG.

(5 pins)
