Data Sheet
In operating modes that provide address recognition, the high/low byte of the received
address is compared with the individually programmable values in register RAH2/
RAL2/RAH1/RAL1.
This addresses can be masked on a per bit basis by setting the corresponding bits in
registers

Receive Address 1 Byte High
In HDLC Automode bit ’1’ is reserved for ’CRI’ (Command Response
Interpretation). In all other modes
CRI
The setting of this bit effects the meaning of the ’C/R’ bit in the receive
status byte (RSTA). This status bit ’C/R’ should be interpreted after
reception as follows:
’0’ (if ’CRI’=’1’) ;
’1’ (if ’CRI’=’1’) ;
Note: If 1-byte address field is selected in HDLC Automode,
Receive Address 1 Byte Low
The general function and its meaning depends on the selected HDLC
operating mode:
• Automode / Address Mode 2 (16-bit address)
• Automode / Address Mode 2 (8-bit address)
