Description
Port 0: Port 0 is a 32-bit I/O port with individual direction controls for each bit. The
operation of port 0 pins depends upon the pin function selected via the Pin
Connect block.
P0[0] — General purpose digital input/output pin.
RD1 — CAN1 receiver input.
TXD3 — Transmitter output for UART3.
SDA1 — I
P0[1] — General purpose digital input/output pin.
TD1 — CAN1 transmitter output.
RXD3 — Receiver input for UART3.
SCL1 — I
P0[2] — General purpose digital input/output pin.
TXD0 — Transmitter output for UART0.
P0[3] — General purpose digital input/output pin.
RXD0 — Receiver input for UART0.
P0[4] — General purpose digital input/output pin.
I2SRX_CLK — Receive Clock. It is driven by the master and received by the
slave. Corresponds to the signal SCK in the I
RD2 — CAN2 receiver input.
CAP2[0] — Capture input for Timer 2, channel 0.
P0[5] — General purpose digital input/output pin.
I2SRX_WS — Receive Word Select. It is driven by the master and received by
the slave. Corresponds to the signal WS in the I
TD2 — CAN2 transmitter output.
CAP2[1] — Capture input for Timer 2, channel 1.
P0[6] — General purpose digital input/output pin.
I2SRX_SDA — Receive data. It is driven by the transmitter and read by the
receiver. Corresponds to the signal SD in the I
SSEL1 — Slave Select for SSP1.
MAT2[0] — Match output for Timer 2, channel 0.
P0[7] — General purpose digital input/output pin.
I2STX_CLK — Transmit Clock. It is driven by the master and received by the
slave. Corresponds to the signal SCK in the I
SCK1 — Serial Clock for SSP1.
MAT2[1] — Match output for Timer 2, channel 1.
P0[8] — General purpose digital input/output pin.
I2STX_WS — Transmit Word Select. It is driven by the master and received by
the slave. Corresponds to the signal WS in the I
MISO1 — Master In Slave Out for SSP1.
MAT2[2] — Match output for Timer 2, channel 2.
