CAP0.0 Capture input for TIMER0, channel 0.
Port 1: Port 1 is a 32-bit bi-directional 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.
Only pins 16 through 31 of port 1 are available.
Note: All Port 1 pins are 5V tolerant with built-in pull-up resistor that sets input level to high when
corresponding pin is used as input.
P1.16 TRACEPKT0Trace Packet, bit 0. Standard I/O port with internal pull-up.
P1.17 TRACEPKT1Trace Packet, bit 1. Standard I/O port with internal pull-up.
P1.18 TRACEPKT2Trace Packet, bit 2. Standard I/O port with internal pull-up.
P1.19 TRACEPKT3Trace Packet, bit 3. Standard I/O port with internal pull-up.
P1.20 TRACESYNCTrace Synchronization. Standard I/O port with internal pull-up. LOW on
this pin while RESET is LOW enables pins P1.25:16 to operate as a
Trace port after reset.
Important: LOW on pin P1.20 while RESET is LOW enables pins P1.25:16 to
operate as a Trace port after reset.
