Command/Response
Significant only if 2-byte address mode has been selected.
Value of the C/R bit (bit 1 of high address byte) in the received frame.
The interpretation depends on the setting of the ’CRI’ bit in the
register (See “RAH1” on page 203.).
Low Byte Address Compare
Significant in automode and address mode 2 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 addresses (RAL1, RAL2).
LA=’0’

According to the X.25 LAPB protocol,
of a COMMAND frame and
RESPONSE frame.
Parity
This bit carries the parity bit of the last received character.
Framing Error
A character framing error was detected, i.e. a ’0’ was sampled at a bit
position where a stop bit ’1’ was expected due to the selected character
format.
Parity Error
The calculated parity did not match the received parity bit. Optionally the
interrupt PERR can be generated.
