RDOV Receive Data Overflow
A "1" indicates that the D_RFIFO is overflow. The incoming data will overwrite data in the receive
FIFO. The data overflow condition will set both the status and interrupt bits. It is recommended that
software must read the RDOV bit after reading data from D_RFIFO at RMR or RME interrupt. The
software must abort the data and issue a RRST command to reset the receiver if RDOV = 1. The
frame overflow condition will not set this bit.
CRCE CRC Error
This bit indicates the result of frame CRC check:
0: CRC correct
1: CRC error
RMB Receive Message Aborted
A "1" means that a sequence of seven 1's was received and the frame is aborted. Software must
issue RRST command to reset the receiver.
Note: Normally D_RSTA register should be read by the micro-processor after a D_RME interrupt. The contents of D_RSTA are
valid only after a D_RME interrupt and remain valid until the frame is acknowledged via a RACK bit.

This register masks(disables) the first byte address comparison of the incoming frame. If the mask bit
is "1" the corresponding bit comparisons with D_SAP1, D_SAP2 are disabled. Comparison with
SAPG is always performed.
Note: For the LAPD frame, the least significant two bits are the C/R bit and EA = 0 bit. It is suggested that the comparison with
C/R bit be masked. EA = 0 for two octet address frame e.g LAPD, EA = 1 for one octet address frame.

This register contains the first choice of the first byte address of received frame. For LAPD frame,
SA17 - SA12 is the SAPI value, SA11 is C/R bit and SA10 is zero.
