2.0 Register Set
* Depends on state of ADD pins see Section 2.3 "Device Number".
2.2 DEVICE RESET OPERATION
A Device Reset operation is performed in the following conditions:
The Device Reset operation performs the following:
2.3 DEVICE NUMBER (Addr: 000 000; 00h)
This register is used to specify a unique address for each device on the bus.
Reg Add
The value of [AS2:AS0] is determined by the setting of the ADD input pin:
The value of [AS2:AS0] will directly change and follow the value determined by ADD. Since this is a read only register the value
of the address cannot be changed by software.
2.4 MANUFACTURER ID (Addr: 000 001; 01h)
The manufacturer ID matches that assigned to National Semiconductor by the PCI SIG. This register may be used to identify the
manufacturer of the device in order to perform manufacturer specific operations.
• At device power-up.
• When the Reset bit in the Device Control register is set to 1 (see Section 2.8 "Device Control").
• Aborts any device operation in progress and restarts device operation.
• Sets all device registers to their "Reset" (default) value.
