Product data sheet Rev. 04 — 16 October 2007 11 of 39 NXP Semiconductors LPC2131/32/34/36/38 Single-chip 16/32-bit microcontrollers P0.22/AD1.7/ CAP0.0/MAT0.0 2[4] I AD1.7 — ADC 1, input 7. This analog input is always connected to its pin. Available in LPC2134/36/38 only. I CAP0.0 — Capture input for Timer 0, channel 0. O MAT0.0 — Match output for Timer 0, channel 0. P0.23 58[1] I/O General purpose digital input/output pin. P0.25/AD0.4/ AOUT 9[5] I AD0.4 — ADC 0, input 4. This analog input is always connected to its pin. O AOUT — DAC output. Not available in LPC2131. P0.26/AD0.5 10[4] I AD0.5 — ADC 0, input 5. This analog input is always connected to its pin. P0.27/AD0.0/ CAP0.1/MAT0.1 11[4] I AD0.0 — ADC 0, input 0. This analog input is always connected to its pin. I CAP0.1 — Capture input for Timer 0, channel 1. O MAT0.1 — Match output for Timer 0, channel 1. P0.28/AD0.1/ CAP0.2/MAT0.2 13[4] I AD0.1 — ADC 0, input 1. This analog input is always connected to its pin. I CAP0.2 — Capture input for Timer 0, channel 2. O MAT0.2 — Match output for Timer 0, channel 2. P0.29/AD0.2/ CAP0.3/MAT0.3 14[4] I AD0.2 — ADC 0, input 2. This analog input is always connected to its pin. I CAP0.3 — Capture input for Timer 0, channel 3. O MAT0.3 — Match output for Timer 0, channel 3. P0.30/AD0.3/ EINT3/CAP0.0 15[4] I AD0.3 — ADC 0, input 3. This analog input is always connected to its pin. I EINT3 — External interrupt 3 input. I CAP0.0 — Capture input for Timer 0, channel 0. P0.31 17[6] O General purpose digital output only pin. Important: This pin MUST NOT be externally pulled LOW when RESET pin is LOW or the JTAG port will be disabled. P1.0 to P1.31 I/O Port 1: Port 1 is a 32-bit bidirectional I/O port with individual direction controls for each bit. The operation of port 1 pins depends upon the pin function selected via the pin connect block. Pins 0 through 15 of port 1 are not available. P1.16/ TRACEPKT0 16[6] O TRACEPKT0 — Trace Packet, bit 0. Standard I/O port with internal pull-up. P1.17/ TRACEPKT1 12[6] O TRACEPKT1 — Trace Packet, bit 1. Standard I/O port with internal pull-up. P1.18/ TRACEPKT2 8[6] O TRACEPKT2 — Trace Packet, bit 2. Standard I/O port with internal pull-up. P1.19/ TRACEPKT3 4[6] O TRACEPKT3 — Trace Packet, bit 3. Standard I/O port with internal pull-up. P1.20/ TRACESYNC 48[6] O TRACESYNC — Trace Synchronization. Standard I/O port with internal pull-up. LOW on TRACESYNC while RESET is LOW enables pins P1.25:16 to operate as Trace port after reset. P1.21/ PIPESTAT0 44[6] O PIPESTAT0 — Pipeline Status, bit 0. Standard I/O port with internal pull-up. P1.22/ PIPESTAT1 40[6] O PIPESTAT1 — Pipeline Status, bit 1. Standard I/O port with internal pull-up. P1.23/ PIPESTAT2 36[6] O PIPESTAT2 — Pipeline Status, bit 2. Standard I/O port with internal pull-up. Table 3. Pin description …continued Symbol Pin Type Description |
