Single-chip 16-bit/32-bit micro
P0[9]/
I2STX_SDA/
MOSI1/MAT2[3]
A13
[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]
L10
[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]
P12
[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]
J4
[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]
J5
[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), 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.
I/O MOSI1 — Master Out Slave In for SSP1.
I AD0[7] — A/D converter 0, input 7.
P0[14]/
USB_HSTEN2
/
USB_CONNECT2/
SSEL1
M5
[1]
I/O P0[14] — General purpose digital input/output pin.
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 resistor under software control. Used with the SoftConnect
USB feature.
I/O SSEL1 — Slave Select for SSP1.
P0[15]/TXD1/
SCK0/SCK
H13
[1]
I/O P0[15] — General purpose digital input/output pin.
O TXD1 — Transmitter output for UART1.
I/O SCK0 — Serial clock for SSP0.
I/O SCK — Serial clock for SPI.
P0[16]/RXD1/
SSEL0/SSEL
H14
[1]
I/O P0[16] — General purpose digital input/output pin.
I RXD1 — Receiver input for UART1.
I/O SSEL0 — Slave Select for SSP0.
I/O SSEL — Slave Select for SPI.
