Receive Compare Modes
Data Format
Compare Functions
Figure 25-12. Receive Compare Modes
Compare 0 can be one start event of the Receiver. In this case, the receiver compares at each
new sample the last FSLEN bits received at the FSLEN lower bit of the data contained in the
Compare 0 Register (RC0R). When this start event is selected, the user can program the
Receiver to start a new data transfer either by writing a new Compare 0, or by receiving continu-
ously until Compare 1 occurs. This selection is done with the bit (STOP) in RCMR.
The data framing format of both the transmitter and the receiver are programmable through the
Transmitter Frame Mode Register (TFMR) and the Receiver Frame Mode Register (RFMR). In
either case, the user can independently select:
Additionally, the transmitter can be used to transfer synchronization and select the level driven
on the TX_DATA pin while not in data transfer operation. This is done respectively by the Frame
Sync Data Enable (FSDEN) and by the Data Default Value (DATDEF) bits in TFMR.
• the event that starts the data transfer (START)
• the delay in number of bit periods between the start event and the first data bit (
• the length of the data (DATLEN)
• the number of data to be transferred for each start event (DATNB).
• the length of synchronization transferred for each start event (FSLEN)
• the bit sense: most or lowest significant bit first (MSBF).
