DETAILED DESCRIPTION

FUNCTION

General Purpose I/O Group A

PA0 - 7

O42/OD4

General Purpose I/O Port A.

An output-only port. The type of output can

be selected using the PAOD bit, configured

through the network. PAOD = 0 selects

push-pull; PAOD = 1 selects open-drain

(default).

General Purpose I/O Group B

PB0 - 7

O42/OD4

General Purpose I/O Port B.

An output-only port. The type of output can

be selected using PBOD bit, configured

through the network. PBOD = 0 selects

push-pull; PBOD = 1 selects open-drain

(default).

General Purpose I/O Group C

PC0

IT/O42/OD4 General Purpose I/O Port Bit 0.

A bi-directional port. The port direction can

be specified using the shared pin PGS0.

PGS0 = L specifies input; PGS0 = H

specifies output. The type of output can be

selected using PCOD bit, configured

through the network. PCOD = 0 selects

push-pull; PCOD = 1 selects open-drain

(default).

nPISTR1

PC1 - 7

IT

IT/O42/OD4

External Trigger Input 1

The input pin for external trigger signal. If

the shared pin PGS0 is set to L while "6h"

or “7” is set using TXTRG3 - 0 bits that are

configured through network then this port is

configured for the external trigger input.

General Purpose I/O port C bit 1 to 7.

A bi-directional port. The direction of port

and the type of output are configured using

the same way as PC0.
