Description
AD1.7 — A/D converter 1, input 7. This analog input is always connected to
its pin. Available in LPC2138 only.
CAP0.0 — Capture input for Timer 0, channel 0.
MAT0.0 — Match output for Timer 0, channel 0.
General purpose digital input/output pin.
AD0.4 — A/D converter 0, input 4. This analog input is always connected to
its pin.
AOUT — D/A converter output. Available in LPC2132 and LPC2138 only.
AD0.5 — A/D converter 0, input 5. This analog input is always connected to
its pin.
AD0.0 — A/D converter 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 — A/D converter 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 — A/D converter 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 — A/D converter 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 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. 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.
