XAC ... Transmitter Active
The HDLC-transmitter is active when XAC = 1. This bit may be polled. The XAC-bit is
active when:
– either an XTF/XIF-command is issued and the frame has not been completely
– or the transmission of an S-frame is internally initiated and not yet completed.
OV ... Overflow
A “1” in this bit position indicates a message longer than 4095 bytes.
RBC8-11 ... Receive Byte Count
Four most significant bits of the total number of bytes in a received message.
4.3.20
Value after reset: 0XXX0000
RBCHD
Note: Normally RBCHD and RBCLD should be read by the processor after an RME-

transmitted
interrupt in order to determine the number of bytes to be read from the RFIFOD,
and the total message length. The contents of the registers are valid only after an
RME-interrupt, and remain so until the frame is acknowledged via the RMC-bit.
