P0.31

17[6]

General purpose digital output only pin.

Important: This pin MUST NOT be externally pulled LOW when RESET pin is LOW or

the JTAG port will be disabled.

P1.0 to P1.31

I/O

Port 1: Port 1 is a 32-bit bidirectional I/O port with individual direction controls for each

bit. The operation of port 1 pins depends upon the pin function selected via the pin

connect block. Pins 0 through 15 of port 1 are not available.

P1.16/

TRACEPKT0

16[6]

TRACEPKT0 — Trace Packet, bit 0. Standard I/O port with internal pull-up.

P1.17/

TRACEPKT1

12[6]

TRACEPKT1 — Trace Packet, bit 1. Standard I/O port with internal pull-up.

P1.18/

TRACEPKT2

8[6]

TRACEPKT2 — Trace Packet, bit 2. Standard I/O port with internal pull-up.

P1.19/

TRACEPKT3

4[6]

TRACEPKT3 — Trace Packet, bit 3. Standard I/O port with internal pull-up.

P1.20/

TRACESYNC

48[6]

TRACESYNC — Trace Synchronization. Standard I/O port with internal pull-up. LOW

on TRACESYNC while RESET is LOW enables pins P1.25:16 to operate as Trace port

after reset.

P1.21/

PIPESTAT0

44[6]

PIPESTAT0 — Pipeline Status, bit 0. Standard I/O port with internal pull-up.
