2.0 Register Set
* Depends on state of ADD pins see Table 1.
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 00o)
This register is used to specify a unique address for each device on the bus.
The value of AS2:AS0 is determined by the setting of the ADD0 and ADD1 input pins:
The value of AS2:AS0 will directly change and follow the value determined by ADD1:ADD0. Since this is a read only register the
value of the address cannot be changed by software.
2.4 MANUFACTURER ID (Addr 01o)
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.
2.5 DEVICE ID (Addr 02o)
The device ID is defined by the manufacturer of the device and is unique for each device produced by a manufacturer. Bits 15-11
identify the revision number of die and will be incremented upon revision of the device.
• 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.
