AIN3 — A/D converter, input 3. This analog input is always connected to its pin.
EINT3 — External interrupt 3 input.
CAP0[0] — Capture input for Timer 0, channel 0.
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.
Trace Packet, bit 0. Standard I/O port with internal pull-up.
Trace Packet, bit 1. Standard I/O port with internal pull-up.
Trace Packet, bit 2. Standard I/O port with internal pull-up.
Trace Packet, bit 3. Standard I/O port with internal pull-up.
Trace Synchronization. Standard I/O port with internal pull-up.
Note: LOW on this pin while RESET is LOW, enables pins P1[25:16] to operate as
Trace port after reset.
Pipeline Status, bit 0. Standard I/O port with internal pull-up.
Pipeline Status, bit 1. Standard I/O port with internal pull-up.
Pipeline Status, bit 2. Standard I/O port with internal pull-up.
Trace Clock. Standard I/O port with internal pull-up.
External Trigger Input. Standard I/O with internal pull-up.
Returned Test Clock output. Extra signal added to the JTAG port. Assists debugger
synchronization when processor frequency varies. Bidirectional pin with internal
pull-up.
Note: LOW on this pin while RESET is LOW, enables pins P1[31:26] to operate as
Debug port after reset.
Test Data out for JTAG interface.
Test Data in for JTAG interface.
Test Clock for JTAG interface. This clock must be slower than
(CCLK) for the JTAG interface to operate.
Test Mode Select for JTAG interface.
Test Reset for JTAG interface.
CAN1 transmitter output.
external reset input; a LOW on this pin resets the device, causing I/O ports and
peripherals to take on their default states, and processor execution to begin at
address 0. TTL with hysteresis, 5 V tolerant.
input to the oscillator circuit and internal clock generator circuits.
output from the oscillator amplifier.
ground: 0 V reference.
