Function

SPI Peripheral Receive Timeout interrupt is setting irrespective of RXFIFO data

Description

When using SPI timeout interrupt, the RXTIMEOUT counter started decrementing from the point that peripheral is stopped receiving SPI clock and setting the RXTIMEOUT interrupt irrespective of data exists in RXFIFO or not, which does not match the description in the TRM: SPI peripheral receive timeout(RTOUT) interrupt is "asserted when the receive FIFO is not empty, and no further data is received in the specified time at CTL1.RXTIMEOUT.

Workaround

Repeat load RXTIMEROUT counter value while receive FIFO is empty, and start timeout counting only when receive FIFO gets any data.
