LPC11Cx2/Cx4
32-bit ARM Cortex-M0 microcontroller
R/PIO1_0/AD1/
CT32B1_CAP0
33
[5]
yes - I; PU R — Reserved. Configure for an alternate function in the IOCONFIG
block.
I/O - PIO1_0 — General purpose digital input/output pin.
I- AD1 — A/D converter, input 1.
I- CT32B1_CAP0 — Capture input 0 for 32-bit timer 1.
R/PIO1_1/AD2/
CT32B1_MAT0
34
[5]
no - I; PU R — Reserved. Configure for an alternate function in the IOCONFIG
block.
I/O - PIO1_1 — General purpose digital input/output pin.
I- AD2 — A/D converter, input 2.
O- CT32B1_MAT0 — Match output 0 for 32-bit timer 1.
R/PIO1_2/AD3/
CT32B1_MAT1
35
[5]
no - I; PU R — Reserved. Configure for an alternate function in the IOCONFIG
block.
I/O - PIO1_2 — General purpose digital input/output pin.
I- AD3 — A/D converter, input 3.
O- CT32B1_MAT1 — Match output 1 for 32-bit timer 1.
SWDIO/PIO1_3/
AD4/
CT32B1_MAT2
39
[5]
no I/O I; PU SWDIO — Serial wire debug input/output.
I/O - PIO1_3 — General purpose digital input/output pin.
I- AD4 — A/D converter, input 4.
O- CT32B1_MAT2 — Match output 2 for 32-bit timer 1.
PIO1_4/AD5/
CT32B1_MAT3/
WAKEUP
40
[5]
no I/O I; PU PIO1_4 — General purpose digital input/output pin with 10 ns glitch
filter.
I- AD5 — A/D converter, input 5.
O- CT32B1_MAT3 — Match output 3 for 32-bit timer 1.
I- WAKEUP — Deep power-down mode wake-up pin with 20 ns glitch
filter. This pin must be pulled HIGH externally to enter Deep
power-down mode and pulled LOW to exit Deep power-down mode.
A LOW-going pulse as short as 50 ns wakes up the part.
