LPC2212/2214

16/32-bit ARM microcontrollers

P0[14]/DCD1/EINT1

DCD1 — Data Carrier Detect input for UART1.

EINT1 — External interrupt 1 input.

Note: LOW on this pin while RESET is LOW forces on-chip bootloader to take

over control of the part after reset.

P0[15]/RI1/EINT2

RI1 — Ring Indicator input for UART1.

EINT2 — External interrupt 2 input.

P0[16]/EINT0/MAT0[2]/

CAP0[2]

100

EINT0 — External interrupt 0 input.

MAT0[2] — Match output for Timer 0, channel 2.

CAP0[2] — Capture input for Timer 0, channel 2.

P0[17]/CAP1[2]/SCK1/

MAT1[2]

101

CAP1[2] — Capture input for Timer 1, channel 2.

I/O

SCK1 — Serial Clock for SPI1/SSP[1]. SPI clock output from master or input

to slave.

MAT1[2] — Match output for Timer 1, channel 2.

P0[18]/CAP1[3]/MISO1/

MAT1[3]

121

CAP1[3] — Capture input for Timer 1, channel 3.

I/O

MISO1 — Master In Slave Out for SPI1/SSP[1]. Data input to SPI master or

data output from SPI slave.

MAT1[3] — Match output for Timer 1, channel 3.

P0[19]/MAT1[2]/MOSI1/

CAP1[2]

122

MAT1[2] — Match output for Timer 1, channel 2.

I/O

MOSI1 — Master Out Slave In for SPI1/SSP[1]. Data output from SPI master

or data input to SPI slave.

CAP1[2] — Capture input for Timer 1, channel 2.

P0[20]/MAT1[3]/SSEL1/

EINT3

123

MAT1[3] — Match output for Timer 1, channel 3.

SSEL1 — Slave Select for SPI1/SSP[1]. Selects the SPI interface as a slave.

EINT3 — External interrupt 3 input.

P0[21]/PWM5/CAP1[3]

PWM5 — Pulse Width Modulator output 5.

CAP1[3] — Capture input for Timer 1, channel 3.

P0[22]/CAP0[0]/MAT0[0] 5

CAP0[0] — Capture input for Timer 0, channel 0.

MAT0[0] — Match output for Timer 0, channel 0.

P0[23]

I/O

General purpose bidirectional digital port only.

P0[24]

I/O

General purpose bidirectional digital port only.

P0[25]
