Transmit Address Byte 2 (WRITE)
Second individually programmable address byte.
Note:
Receive Byte Count Low (READ)
RBCL
Together with RBCH (bits RBC11 – RBC8), the length of the actual received frame
(1…4095 bytes) can be determined. These registers must be read by the CPU following an
RME interrupt.

XAD2 2-byte address
– –
– –
2-byte address (MODE.ADM = 1)
XAD2 builds up the low byte of the 2-byte address field
(In the ISDN, the low address byte is known as TEI)
1-byte address (MODE.ADM = 0)
According to the X.25 LAPB protocol, XAD2 indicates a RESPONSE,
XAD1, XAD2 registers are used only if the HSCX is operated in auto-mode.
