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
2
C1 data input/output (this is not an open-drain pin).
P0[1] —
General purpose digital input/output pin.
TD1 —
CAN1 transmitter output.
RXD3 —
Receiver input for UART3.
SCL1 —
I
2
C1 clock input/output (this is not an open-drain pin).
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 —
I
2
S Receive clock. It is driven by the master and received
by the slave. Corresponds to the signal SCK in the
I
2
S-bus
specification
.
[15]

CAP2[0] —
Capture input for Timer 2, channel 0.
P0[5] —
General purpose digital input/output pin.
I2SRX_WS —
I
2
S Receive word select. It is driven by the master and
received by the slave. Corresponds to the signal WS in the
I
2
S-bus
specification
.
[15]
LCDVD[1] —
LCD data.
[15]
TD2 —
CAN2 transmitter output.
CAP2[1] —
Capture input for Timer 2, channel 1.
P0[6] —
General purpose digital input/output pin.
I2SRX_SDA —
I
2
S Receive data. It is driven by the transmitter and read
by the receiver. Corresponds to the signal SD in the
I
2
S-bus
specification
.
[15]
LCDVD[8] —
LCD data.
[15]
SSEL1 —
Slave Select for SSP1.
