Table 4. Pin description
Symbol Pin Type Description
P0[0] to P0[31] I/O 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. Some port pins are not available on the LQFP80 package.
P0[0]/RD1/TXD3/
SDA1
37
[1]
I/O P0[0] — General purpose digital input/output pin.
I RD1 — CAN1 receiver input.
O TXD3 — Transmitter output for UART3.
I/O SDA1 — I
2
C1 data input/output (this is not an I
2
C-bus compliant open-drain pin).
P0[1]/TD1/RXD3/
SCL1
38
[1]
I/O P0[1] — General purpose digital input/output pin.
O TD1 — CAN1 transmitter output.
I RXD3 — Receiver input for UART3.
I/O SCL1 — I
2
C1 clock input/output (this is not an I
2
C-bus compliant open-drain pin).
P0[2]/TXD0/AD0[7] 79
[2]
I/O P0[2] — General purpose digital input/output pin.
O TXD0 — Transmitter output for UART0.
I AD0[7] — A/D converter 0, input 7.
P0[3]/RXD0/AD0[6] 80
[2]
I/O P0[3] — General purpose digital input/output pin.
I RXD0 — Receiver input for UART0.
I AD0[6] — A/D converter 0, input 6.
P0[6]/
I2SRX_SDA/
SSEL1/MAT2[0]
64
[1]
I/O P0[6] — General purpose digital input/output pin.
I/O I2SRX_SDA — Receive data. It is driven by the transmitter and read by the
receiver. Corresponds to the signal SD in the I
