SLVTOCNT
Slave Mode Time-out Period (Only Supported in SPI0)
In Slave mode, these bits indicate the time-out period when there is bus clock input during
slave select active. The clock source of the time-out counter is Slave peripheral clock. If the
value is 0, it indicates the slave mode time-out function is disabled.

SLVTORST
Slave Mode Time-out Reset Control (Only Supported in SPI0)
0 = When Slave mode time-out event occurs, the TX and RX control circuit will not be reset.
1 = When Slave mode time-out event occurs, the TX and RX control circuit will be reset by
hardware.
