The B2 channel HDLC register's definitions and functions are the same as those of B1 channel HDLC. Please refer to section
8.2 for a detailed description.
8.4 PCI Configuration Register
W6692 provides PCI interface for PCI-base system and only supports slave mode. There are two optional Base Address
Registers (Memory or I/O) for host access to W6692 internal registers.
Reads to reserved or unimplemented registers return data value of 0. Write to these registers are completed normally and the
data are discarded.
After power on reset, W6692 automatically reads the configuration data from serial EEPROM interface. The first word read is
Vendor ID. If Vendor ID = FFFF_H, W6692 assumes EEPROM is empty and will use built-in default configuration data,
otherwise, configuration data from EEPROM is used. Please refer to Section 7.9.1 for serial EEPROM data format.
