LPC2377/78
Single-chip 16-bit/32-bit microcontrollers
P0[9]/
I2STX_SDA/
MOSI1/MAT2[3]
109
[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]
69
[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 pin is not open-drain).
O MAT3[0] — Match output for Timer 3, channel 0.
P0[11]/RXD2/
SCL2/MAT3[1]
70
[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 pin is not open-drain).
O MAT3[1] — Match output for Timer 3, channel 1.
P0[12]/MISO1/
AD0[6]
29
[2]
I/O P0[12] — General purpose digital input/output pin.
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]
32
[2]
I/O P0[13] — General purpose digital input/output pin.
O USB_UP_LED2 — USB2 Good Link LED indicator. It is LOW when device is
configured (non-control endpoints enabled), or when host is enabled and has
detected a device on the bus. It is HIGH when the device is not configured, or when
host is enabled and has not detected a device on the bus, or during global suspend.
It transitions between LOW and HIGH (flashes) when host is enabled and detects
activity on the bus. (LPC2378 only)
I/O MOSI1 — Master Out Slave In for SSP1.
I AD0[7] — A/D converter 0, input 7.
P0[14]/
USB_CONNECT2/
SSEL1
48
[1]
I/O P0[14] — General purpose digital input/output pin.
O USB_CONNECT2 — USB2 Soft Connect control. Signal used to switch an external
1.5 k resistor under software control. Used with the SoftConnect USB feature.
(LPC2378 only)
I/O SSEL1 — Slave Select for SSP1.
P0[15]/TXD1/
SCK0/SCK
89
[1]
