Description

GPIO00-07 2-9

I/O

INTS/

OD6,O3/6

VDD

General-Purpose I/O Port 0, bits 0-7. Each pin is configured in-

dependently as input or I/O, with or without static pull-up, and with

either open-drain or push-pull output type. The port support inter-

rupt assertion and each pin can be enabled or masked as an inter-

rupt source.

I/O

INTS/

OD6,O3/6

VDD

General-Purpose I/O Port 1, bits 0-7. Same as Port 0. Bit 5 is

output only with low output as default.

GPIO20-27 117-124 I/O

INTS/

OD6,O3/6

VDD

General-Purpose I/O Port 2, bits 0-7. Similar to port 0, but

without the interrupt assertion capability.

GPIO30-33

GPIO34

125-128

I/O

INTS/

OD6,O3/6

VDD

General-Purpose I/O Port 3, bits 0-4. Similar to port 0, but

without the interrupt assertion capability. Bits 5, 6 and 7 are not

implemented.

GPIO40-47 43-50

I/O

INTS/

OD6,O3/6

VDD

General-Purpose I/O Port 4, bits 0-7. Same as Port 0.

IR Receive 1. Primary input to receive serial data from the IR

transceiver. Monitored during power-off for wake-up event

detection.

IRRX2_IRSL0 58

I/O

INTS/O3/6

VDD,VSB IRRX2 - IR Receive 2. Auxiliary IR receiver input to support a

second transceiver. Monitored during power-off for wake-up event

detection.

IRSL3-0 IR Select. Output are used to control the IR transceivers.

Input for PnP identiﬁcation of plug-in IR transceiver (dongle).

After reset, the dual-function IRSLX pins wake up in input mode.

After the ID is read by the IR driver, they may be put into output

mode. The output mode is controlled by Serial Port 2.
