Data Sheet
W6692A PCI ISDN S/T-Controller
Publication Release Date:
Mar,2000
Revision 1.0
-82 -
This value is loaded from EEPROM after power-on
reset, if EEPROM is not empty.
The default value is 020400 H to specify that the W6692A is an ISDN network communication device, if EEPROM is empty.
Bits 7-0
Revision ID
Read_only
This value is assigned by the ISDN system manufacturer and identifies the revision number of the system.
This value is loaded from EEPROM after power on reset, if EEPROM is not empty.
The default value is 00 H, if EEPROM is empty.

Read_only
This register is always read as 0. It means that W6692A does not support BIST function.
Bits 23-16
Header Type
Read_only
The value of this register is 00H. This means a signle function device, with header type 00H.
Bits 15-8
