The four MSB of the FSLEN field.
Determines which edge on Frame Sync will generate the SR.RXSYN interrupt.
This field defines the length of the Receive Frame Sync signal and the number of bits sampled and stored in the RSHR register.
When this mode is selected by the RCMR.START field, it also determines the length of the sampled data to be compared to the
Compare 0 or Compare 1 register.
Note: The four most significant bits for this field are located in the FSLENHI field.
