32.6.1.2 Transmitter Clock Management
The transmitter clock is generated from the receiver clock or the divider clock or an external clock scanned on the
TK I/O pad. The transmitter clock is selected by the CKS field in SSC_TCMR (Transmit Clock Mode Register).
Transmit Clock can be inverted independently by the CKI bits in SSC_TCMR.
The transmitter can also drive the TK I/O pad continuously or be limited to the actual data transfer. The clock
output is configured by the SSC_TCMR. The Transmit Clock Inversion (CKI) bits have no effect on the clock
outputs. Programming the TCMR to select TK pin (CKS field) and at the same time Continuous Transmit Clock
(CKO field) might lead to unpredictable results.
