Subscriber Awake
Used only if terminal specific functions are enabled (STCR:TSF = 1).
Indicates that a falling edge on the EAW line has been detected, in case the terminal
specific functions are enabled (TSF bit in STCR).
Watchdog Timer Overflow
Used only if terminal specific functions are enabled (STCR:TSF = 1).
Signals the expiration of the watchdog timer, which means that the processor has
failed to set the watchdog timer control bits WTC1 and WTC2 (ADF1 register) in the
correct manner. A reset pulse has been generated by the ISAC-S TE.

Used in auto-mode only.
XAD1 contains a programmable address byte which is appended automatically to the
frame by the ISAC-S TE in auto-mode. Depending on the selected address mode
XAD1 is interpreted as follows:
* 2-Byte Address Field
XAD1 is the high byte (SAPI in the ISDN) of the 2-byte address field. Bit 1 is
interpreted as the command/response bit "C/R". It is automatically generated by the
ISAC-S TE following the rules of ISDN LAPD protocol and the CRI bit value in SAP1
register. Bit 1 has to be set to "0".
In the ISDN LAPD the address field extension bit "EA", i.e. bit 0 of XAD1 has to be
set to "0".
* 1-Byte Address Field
According to the X.25 LAPB protocol, XAD1 is the address of a command frame.
Note: In standard ISDN applications only 2-byte address fields are used.
