Address Recognition
Address recognition is performed in three operating modes (auto-mode, non-auto-mode
and transparent mode 1). Two pairs of compare registers (RAH1, RAH2: high byte
compare, RAL1, RAL2: low byte compare) are provided. RAL2 may be used for a
broadcast address. In auto-mode and non-auto-mode 1- or 2-byte address fields are
supported, transparent mode 1 is restricted on high byte recognition. The high byte
address is additionally compared with the LAPD group address (FC
Depending on the operating mode the following combinations are considered valid
addresses:
