• Manufacturer: Freescale Semiconductor, Inc

Byte Data Link Controller-Digital (BDLC-D)
21.5.4.3 Valid Passive Logic 1
21.5.4.4 Valid EOD Symbol
21.5.4.5 Valid EOF and IFS Symbols
Technical Data
See
beginning the next data bit (or symbol) occurs between b and c, the
current bit would be considered a logic 1.
See
beginning the next data bit (or symbol) occurs between c and d, the
current symbol would be considered a valid end-of-data symbol (EOD).
In
the SOF symbol of the next message occurs between a and b, the
current symbol will be considered a valid end-of-frame (EOF) symbol.
