High Byte Address Compare
Significant only if 2-byte address mode has been selected.
In operating modes which provide high byte address recognition, the

contents of two individually programmable registers (RAH1, RAH2)
and the fixed values FE
Dependent on the result of this comparison, the following bit
combinations are possible:
Note: If RAH1, RAH2 contain identical values, a match is indicated
Low Byte Address Compare
Significant in HDLC modes only.
The low byte address of a 2-byte address field, or the single address
byte of a 1-byte address field is compared with two registers. (RAL1,
RAL2).
Together with RBCH (bits RBC11...8) indicates the length of a
received frame (1…4095 bytes). Bits RBC4-0 indicate the number of
valid bytes currently in RFIFO. These registers must be read by the
CPU following an RME interrupt.
