GPIO Interface Signals

Signal Name

Ball No.

Type

Description

Mux

GPIO0

D11

I/O

GPIO Port 0. Each signal is configured independently as
an input or I/O, with or without static pull-up, and with
either open-drain or totem-pole output type.

A debouncer and an interrupt can be enabled or masked
for each of signals GPIO[00:01] and [06:15] indepen-
dently.

Note:

GPIO12, GPIO13, GPIO16 inputs: If GPIOx func-
tion is selected but not used, tie GPIOx low.

I/O

GPIO Port 1. Each signal is configured independently as
an input or I/O, with or without static pull-up, and with
either open-drain or totem-pole output type.

A debouncer and an interrupt can be enabled or masked
for each of signals GPIO[32:41] independently.
