TSIFR — Transmit Single Byte IFR with No CRC (Type 1 or 2) Bit
If the programmer attempts to set the TSIFR bit immediately after the
EOD symbol has been received from the bus, the TSIFR bit will remain
in the reset state and no attempt will be made to transmit the IFR byte.
If a loss of arbitration occurs when the BDLC attempts to transmit and
after the IFR byte winning arbitration completes transmission, the BDLC
DATA FIELD
DATA FIELD
The TSIFR bit is used to request the BDLC to transmit the byte in the
BDLC data register (BDR) as a single byte IFR with no CRC.
Typically, the byte transmitted is a unique identifier or address of the
transmitting (responding) node. See
