Preliminary W6691
Publication Release Date: Sep 2001
94 Revision 1.1
RBC7-0 Receive Byte Count
Used in transparent mode only. Eight least significant bits of the total number of bytes are in a received frame.
These bits are valid only after a RME interrupt and remain valid until the frame is acknowledge via the RACK
bit.

LOV Message Length Overflow
Used in transparent mode only. A "1" in this bit indicates a received message
≥
8192 bytes. This bit is valid
only after RME interrupt and is cleared by the RACK command.
RBC12-8 Receive Byte Count
Used in transparent mode only. Five most significant bits of the total number of bytes are in a received frame.
These bits are valid only after a RME interrupt and remain valid until the frame is acknowledge via the RACK
bit.
Note
: The frame length equals RBC12-0. This length is between 1 and 8191. After a RME interrupt, the
number of data available in B1_RFIFO is frame length modulus threshold.
Remainder = RBC12-0 MOD threshold
No of available data = remainder if remainder
≠
0 or
No of available data = threshold if remainder = 0
The remainder equals RBC5-0 if threshold is 64.

This pattern is transmitted when the transmitter is active and transmit FIFO is empty. Valid in extended
transparent mode only.
