purpose I/O pins. The SSI_IO1 and SSI_IO2 external
pins may be used as general purpose I/O by proper con-
figuration of the SSI_CTL register, or they may be used
as transmit clock input and as transmit framing signal in-
put or output. The SSI_CTL.IO1 and SSI_CTL.IO2 Mode
Select fields control the direction and functionality of
these two pins.

A hardware reset or a software reset of the transmitter
through SSI_CTL.TXR command sets the SSI_CTL.IO1
and SSI_CTL.O2 fields to 11b, a conflict-free initial pin
state.Table 17-2

on SSI_IO2. Note: If SSI_IO1 is not selected as transmit
clock input, the transmit clock is taken from the receive
clock signal instead. If SSI_IO2 is not selected as trans-
mit framing signal input or output, the transmit framing
signal is taken from the receive framing signal instead.
