pin.

MCOB2 — Motor control PWM channel 2, output B.

R — Function reserved.

I/O

I2S0_TX_SDA — I2S transmit data. It is driven by the

transmitter and read by the receiver. Corresponds to

the signal SD in the I2S-bus specification.

ENET_RXD3 — Ethernet receive data 3 (MII

interface).

R — Function reserved.

I/O

SSP0_MOSI — Master Out Slave in for SSP0.
