Description
General purpose digital input/output pin.
AD0.4 — ADC 0, input 4. This analog input is always connected to its pin.
AOUT — DAC output. Not available in LPC2131.
AD0.5 — ADC 0, input 5. This analog input is always connected to its pin.
AD0.0 — ADC 0, input 0. This analog input is always connected to its pin.
CAP0.1 — Capture input for Timer 0, channel 1.
MAT0.1 — Match output for Timer 0, channel 1.
AD0.1 — ADC 0, input 1. This analog input is always connected to its pin.
CAP0.2 — Capture input for Timer 0, channel 2.
MAT0.2 — Match output for Timer 0, channel 2.
AD0.2 — ADC 0, input 2. This analog input is always connected to its pin.
CAP0.3 — Capture input for Timer 0, channel 3.
MAT0.3 — Match output for Timer 0, channel 3.
AD0.3 — ADC 0, 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.
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.
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.
TRACEPKT0 — Trace Packet, bit 0. Standard I/O port with internal pull-up.
TRACEPKT1 — Trace Packet, bit 1. Standard I/O port with internal pull-up.
TRACEPKT2 — Trace Packet, bit 2. Standard I/O port with internal pull-up.
TRACEPKT3 — Trace Packet, bit 3. Standard I/O port with internal pull-up.
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.
PIPESTAT0 — Pipeline Status, bit 0. Standard I/O port with internal pull-up.
PIPESTAT1 — Pipeline Status, bit 1. Standard I/O port with internal pull-up.
PIPESTAT2 — Pipeline Status, bit 2. Standard I/O port with internal pull-up.
TRACECLK — Trace Clock. Standard I/O port with internal pull-up.
EXTIN0 — External Trigger Input. Standard I/O with internal pull-up.
