Receive Compare Modes
Data Framing Format
Compare functions
and Transmit Sync bits in the SR register (SR.RXSYN and SR.TXSYN) on frame synchro edge
detection (signals RX_FRAME_SYNC/TX_FRAME_SYNC).
Figure 20-12. 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 {RFMR.FSLENHI, RFMR.FSLEN} bits received to the {RFMR.FSLENHI,
RFMR.FSLEN} lower bits of the data contained in the Receive 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 continuously until Compare 1 occurs. This
selection is done with the Receive Stop Selection bit in the RCMR register (RCMR.STOP).
The data framing format of both the transmitter and the receiver are programmable through the
TFMR, TCMR, RFMR, and RCMR registers. 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 writing to
the Frame Sync Data Enable and the Data Default Value bits in the TFMR register
(TFMR.FSDEN and TFMR.DATDEF).
Table 20-3.
• the event that starts the data transfer (RCMR.START and TCMR.START)
• the delay in number of bit periods between the start event and the first data bit
• the length of the data (RFMR.DATLEN and TFMR.DATLEN)
• the number of data to be transferred for each start event (RFMR.DATNB and TFMR.DATLEN)
• the length of synchronization transferred for each start event (RFMR.FSLENHI,
• the bit sense: most or lowest significant bit first (RFMR.MSBF and TFMR.MSBF)
