Table 161. LPC1111/12/13/14 pin description table (HVQFN33 package)
Symbol Pin Type Description
PIO0_0 to PIO0_11 I/O Port 0 — Port 0 is a 12-bit I/O port with individual direction and function
controls for each bit. The operation of port 0 pins depends on the function
selected through the IOCONFIG register block.
RESET
/PIO0_0 2
[1][2]
I RESET — 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.
In deep power-down mode, this pin must be pulled HIGH externally. The
RESET pin can be left unconnected or be used as a GPIO pin if an external
RESET
function is not needed.
I/O PIO0_0 — General purpose digital input/output pin.
PIO0_1/CLKOUT/
CT32B0_MAT2
3
[3][2]
I/O PIO0_1 — General purpose digital input/output pin. A LOW level on this pin
during reset starts the ISP command handler.
O CLKOUT — Clock out pin.
O CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
PIO0_2/SSEL0/
CT16B0_CAP0
8
[3][2]
I/O PIO0_2 — General purpose digital input/output pin.
O SSEL0 — Slave select for SPI0.
I CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3 9
[3][2]
I/O PIO0_3 — General purpose digital input/output pin.
PIO0_4/SCL 10
[4][2]
I/O PIO0_4 — General purpose digital input/output pin (open-drain).
I/O SCL — I
2
C-bus, open-drain clock input/output. High-current sink only if I
2
C
Fast-mode Plus is selected in the I/O configuration register.
PIO0_5/SDA 11
[4][2]
I/O PIO0_5 — General purpose digital input/output pin (open-drain).
I/O SDA — I
2
C-bus, open-drain data input/output. High-current sink only if I
2
C
Fast-mode Plus is selected in the I/O configuration register.
PIO0_6/SCK0 15
[3][2]
I/O PIO0_6 — General purpose digital input/output pin.
I/O SCK0 — Serial clock for SPI0.
PIO0_7/CTS
16
[3][2]
I/O PIO0_7 — General purpose digital input/output pin (high-current output
driver).
I CTS
— Clear To Send input for UART.
PIO0_8/MISO0/
CT16B0_MAT0
17
[3][2]
I/O PIO0_8 — General purpose digital input/output pin.
I/O MISO0 — Master In Slave Out for SPI0.
O CT16B0_MAT0 — Match output 0 for 16-bit timer 0.
PIO0_9/MOSI0/
CT16B0_MAT1
18
[3][2]
I/O PIO0_9 — General purpose digital input/output pin.
I/O MOSI0 — Master Out Slave In for SPI0.
O CT16B0_MAT1 — Match output 1 for 16-bit timer 0.
SWCLK/PIO0_10/SCK0/
CT16B0_MAT2
19
[3][2]
I SWCLK — Serial wire clock.
I/O PIO0_10 — General purpose digital input/output pin.
I/O SCK0 — Serial clock for SPI0.
O CT16B0_MAT2 — Match output 2 for 16-bit timer 0.
R/PIO0_11/AD0/
CT32B0_MAT3
21
[5][2]
I 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.
