0 = After completion of a data transfer when starting with a Compare 0, the receiver stops the data transfer and waits for a
new compare 0. 

1 = After starting a receive with a Compare 0, the receiver operates in a continuous mode until a Compare 1 is detected.

If STTDLY is not 0, a delay of STTDLY clock cycles is inserted between the start event and the actual start of reception. When the 
Receiver is programmed to start synchronously with the Transmitter, the delay is also applied.

Note: It is very important that STTDLY be set carefully. If STTDLY must be set, it should be done in relation to TAG (Receive Sync 
Data) reception.

This field selects the divider to apply to the selected Receive Clock in order to generate a new Frame Sync Signal. If 0, no 
PERIOD signal is generated. If not 0, a PERIOD signal is generated each 2 x (PERIOD+1) Receive Clock.

0

Continuous, as soon as the receiver is enabled, and immediately 
after the end of transfer of the previous data.
