transmitter and read by the receiver. Corresponds to the

signal SD in the I2S-bus specification.

I/O

SSP1_SSEL — Slave Select for SSP1.

T2_MAT0 — Match output for Timer 2, channel 0.

U1_RTS — Request to Send output for UART1. Can also

be configured to be an RS-485/EIA-485 output enable

signal for UART1.
