PEB 20534
Serial Communication Controller (SCC) Cores
The transmit clock supplied at pin TxCLK can be switched out to pin RTS in phase with
the transmit data on pin TxD if bit ’TCLKO’ in register CCR1 is set. Due to internal signal
delays the transmit data output signal delay to TxCLK may be high with regard to the total
clock period of 19.2 nanoseconds which is the minimum high speed clock period.
Therefore the transmit clock is supplied to pin RTS such that TxD signal has a small
delay to this monitor clock which might be useful for connection to external transceiver
devices.
