Transmit Address Byte 1 (WRITE)
XAD1 (and XAD2) can be programmed with one individual address byte which is appended
automatically to the frame by HSCX in auto-mode. The function depends on the selected
address mode (bit ADM in MODE).
XAD1 forms the high byte of the 2-byte address field. Bit 1 must be set to 0! According to the
ISDN LAPD protocol, bit 1 is interpreted as the C/R (COMMAND/RESPONSE) bit. This is
manipulated automatically by the HSCX dependent on the setting of the CRI bit in RAH1:
Commands transmit
Responses transmit
(In the ISDN, the high address byte is known as SAPI).
In accordance with the HDLC protocol, bit 0 should be set to 0, indicating the extension of the
address field to two bytes.
