Reset value:
• FSLENHI: Transmit 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 TXSYN (Status Register).
• FSDEN: Frame Sync Data Enable
0: The TX_DATA line is driven with the default value during the Transmit Frame Sync signal.
1: TSHR value is shifted out during the transmission of the Transmit Frame Sync signal.
• FSOS: Transmit Frame Sync Output Selection
• FSLEN: Transmit Frame Sync Length
This field defines the length of the Transmit Frame Sync signal and the number of bits shifted out from the Transmit Sync
Data Register if FSDEN is 1. Note: The four most significant bits fo this bitfield are in the FSLENHI bitfield.
