Chapter 8: LPC24XX Pin configuration
P0[9]/
I2STX_SDA/
MOSI1/MAT2[3] 158 [1] C14 [1] I/O P0[9] — General purpose digital input/output pin.
I/O I2STX_SDA — Transmit data. It is driven by the transmitter and read by
the receiver. Corresponds to the signal SD in the I
2 S-bus specification.
I/O MOSI1 — Master Out Slave In for SSP1.
O MAT2[3] — Match output for Timer 2, channel 3.
P0[10]/TXD2/
SDA2/MAT3[0] 98 [1] T15 [1] I/O P0[10] — General purpose digital input/output pin.
O TXD2 — Transmitter output for UART2.
I/O SDA2 — I 2 C2 data input/output (this is not an open-drain pin).
O MAT3[0] — Match output for Timer 3, channel 0.
P0[11]/RXD2/
SCL2/MAT3[1] 100 [1] R14 [1] I/O P0[11] — General purpose digital input/output pin.
I RXD2 — Receiver input for UART2.
I/O SCL2 — I 2 C2 clock input/output (this is not an open-drain pin).
O MAT3[1] — Match output for Timer 3, channel 1.
P0[12]/
USB_PPWR2/
MISO1/AD0[6] 41 [2] R1 [2] I/O P0[12] — General purpose digital input/output pin.
O USB_PPWR2 — Port Power enable signal for USB port 2.
I/O MISO1 — Master In Slave Out for SSP1.
I AD0[6] — A/D converter 0, input 6.
P0[13]/
USB_UP_LED2/
MOSI1/AD0[7] 45 [2] R2 [2] I/O P0[13] — General purpose digital input/output pin.
O USB_UP_LED2 — USB port 2 GoodLink LED indicator. It is LOW when
device is configured (non-control endpoints enabled). It is HIGH when the
device is not configured or during global suspend.
I/O MOSI1 — Master Out Slave In for SSP1.
I AD0[7] — A/D converter 0, input 7.
P0[14]/
USB_HSTEN2/

O USB_HSTEN2 — Host Enabled status for USB port 2.
O USB_CONNECT2 — SoftConnect control for USB port 2. Signal used to
switch an external 1.5 k
Ω resistor under software control. Used with the
SoftConnect USB feature.
I/O SSEL1 — Slave Select for SSP1.
P0[15]/TXD1/
