I/O Module

9.1

Overview

The I/O Module within the TMPR3911/12 contains support for reading and writing the 7 bi-directional

general purpose I/O pins and the 32 bi-directional multi-function I/O pins.

Each of the general purpose I/O pins can be independently configured as an input or output port. Each port

can generate a separate positive and negative edge interrupt and each port can also be independently

configured to use a debouncer.

Of the 137 signal pins found on the TMPR3911/12, 32 of them are multi-function and can be

independently programmed either as I/O ports or for an alternate standard/normal function. This allows the

TMPR3911/12 to support a flexible and wide range of system applications and configurations. As an I/O

port, any of these pins can be programmed as an input or output port, with the capability of generating a

separate positive and negative edge interrupt.

I/O[6:0]:

INPUT/OUTPUT

These pins are general purpose input/output ports. Each port can be independently programmed

as an input or output port. Each port can generate a separate positive and negative edge interrupt.

Each port can also be independently programmed to use a 16 ms to 24 ms debouncer.

MFIO[1:0]:

INPUT/OUTPUT

These pins are multi-function input/output ports. Each port can be independently programmed as

an input or output port, or can be programmed for multi-function use to support test signals (for

debugging purposes only). Each port can generate a separate positive and negative edge interrupt.

Note that 30 other multi-function pins are available for usage as multi-function input/output ports.

These pins are named according to their respective standard/normal function and are not listed

here.
