Chapter 11: LPC111x Pin configuration (LPC1100XL series,
R/PIO0_11/AD0/
CT32B0_MAT3
21
[5]
yes - I;PU R — Reserved. Configure for an alternate function in the IOCONFIG
block.
I/O - PIO0_11 — General purpose digital input/output pin.
I- AD0 — A/D converter, input 0.
O- CT32B0_MAT3 — Match output 3 for 32-bit timer 0.
PIO1_0 to PIO1_11 Port 1 — Port 1 is a 12-bit I/O port with individual direction and
function controls for each bit. The operation of port 1 pins depends on
the function selected through the IOCONFIG register block.
R/PIO1_0/AD1/
CT32B1_CAP0
22
[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
23
[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
24
[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
25
[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
26
[5]
no I/O I;PU PIO1_4 — General purpose digital input/output pin with 10 ns glitch
filter. In Deep power-down mode, this pin serves as the Deep
power-down mode wake-up pin with 20 ns glitch filter. Pull this pin
HIGH externally before entering Deep power-down mode. Pull this pin
LOW to exit Deep power-down mode. A LOW-going pulse as short as
50 ns wakes up the part.
I- AD5 — A/D converter, input 5.
O- CT32B1_MAT3 — Match output 3 for 32-bit timer 1.
PIO1_5/RTS
/
CT32B0_CAP0
30
[3]
no I/O I;PU PIO1_5 — General purpose digital input/output pin.
O- RTS
— Request To Send output for UART.
I- CT32B0_CAP0 — Capture input 0 for 32-bit timer 0.
PIO1_6/RXD/
CT32B0_MAT0
31
[3]
no I/O I;PU PIO1_6 — General purpose digital input/output pin.
I- RXD — Receiver input for UART.
O- CT32B0_MAT0 — Match output 0 for 32-bit timer 0.
