Reset value:
• FSLENHI: Receive Frame Sync Length High part
The four MSB of the FSLEN bitfield.
• FSEDGE: Frame Sync Edge Detection
Determines which edge on Frame Sync will generate the interrupt RXSYN in the SSC Status Register.
• FSOS: Receive Frame Sync Output Selection
• FSLEN: Receive Frame Sync Length
This field defines the length of the Receive Frame Sync Signal and the number of bits sampled and stored in the Receive
Sync Data Register. When this mode is selected by the START field in the Receive Clock Mode Register, it also deter-
mines the length of the sampled data to be compared to the Compare 0 or Compare 1 register. Note: The four most
significant bits fo this bitfield are in the FSLENHI bitfield.
Pulse length is equal to ({FSLENHI,FSLEN} + 1) Receive Clock periods. Thus, if {FSLENHI,FSLEN} is 0, the Receive
Frame Sync signal is generated during one Receive Clock period.
