Description
6 to 4 RxAlign
Used for reception of bit oriented frames: RxAlign defines the bit position
length for the first bit received to be stored. Further received bits are
stored at the following bit positions.
Example:
RxAlign = 0h - the LSB of the received bit is stored at bit 0, the second
received bit is stored at bit position 1.
RxAlign = 1h - the LSB of the received bit is stored at bit 1, the second
received bit is stored at bit position 2.
RxAlign = 7h - the LSB of the received bit is stored at bit 7, the second
received bit is stored in the following byte at position 0.
Note: If RxAlign = 0, data is received byte-oriented, otherwise
bit-oriented.
3
NoColl
If this bit is set, a collision will result in an IntegErr
2 to 0
RxLastBits Defines the number of valid bits of the last data byte received in
bit-oriented communications. If zero the whole byte is valid.
Note: These bits are set by the RxDecoder in a bit-oriented
communication at the end of the communication. They are reset at start
of reception.
