High Byte Address Compare
Significant only if an address mode with automatic address handling has
been selected. In operating modes which provide high byte address
recognition, SEROCCO-H compares the high byte of a 2-byte address
with the contents of two individually programmable addresses (RAH1,
RAH2) and the fixed values FE
Dependent on the result of this comparison, the following bit
combinations are possible:
HA(1:0)=’10’
HA(1:0)=’00’
HA(1:0)=’01’ broadcast address has been recognized.
If
HA(1:0)=’10’.
SS7 Signaling Unit Type
If Signaling System #7 support is activated (see
’ESS7’), the bit functions are defined as follows:
SU(1:0)=’00’ not valid
SU(1:0)=’01’ Fill In Signaling Unit (FISU) detected
SU(1:0)=’10’ Link Status Signaling Unit (LSSU) detected
SU(1:0)=’11’ Message Signaling Unit (MSU) detected

CRC check failed, received frame contains errors.
CRC check OK; the received frame does not contain CRC
errors.
No abort condition was detected during reception of the
frame.
The received frame was aborted from the transmitting
station. According to the HDLC protocol, this frame must
be discarded by the receiver station.
This bit is also set to ’1’ if the maximum receive byte count
(set in registers RLCRL/RLCRH) is reached.
