LPC2210/2220

16/32-bit ARM microcontrollers

P0.13/DTR1/

MAT1.1

85[1]

H10[1]

DTR1 — Data Terminal Ready output for UART1.

MAT1.1 — Match output for Timer 1, channel 1.

P0.14/DCD1/

EINT1

92[2]

G10[2]

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

99[2]

E11[2]

RI1 — Ring Indicator input for UART1.

EINT2 — External interrupt 2 input.

P0.16/EINT0/

MAT0.2/CAP0.2

100[2]

E10[2]

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[1]

D13[1]

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

I/O

SCK1 — Serial Clock for SPI1/SSI/Microwire.

SPI/SSI/Microwire 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[1]

D8[1]

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

I/O

MISO1 — Master In Slave Out for SPI1. 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[1]

C8[1]

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

I/O

MOSI1 — Master Out Slave In for SPI1. Data output from SPI

master or data input to SPI slave.

• SPI interface: MOSI line.

• SSI: DX/RX line (SPI1 as a master/slave).

• Microwire: SO/SI line (SPI1 as a master/slave).

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

P0.20/MAT1.3/

B8[2]

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

SSEL1 — Slave Select for SPI1/Microwire. Used to select the

SPI or Microwire interface as a slave. Frame synchronization

in case of 4-wire SSI.

EINT3 — External interrupt 3 input.

P0.21/PWM5/
