9.21.12.1 IDCode
The IDCode section shows the raw IDCode read from the device. For example, in the Device Status
report for an AFS600 device, you will find the following statement: IDCode (HEX):
233261cf
The IDCode is compliant to IEEE 1149.1. The following table lists the IDCode bit assignments:
Bit Field (little endian) | Example Bit Value for AFS600 (HEX) | Description |
|---|---|---|
Bit [31-28] (4 bits) | 2 | Silicon Revision |
Bit [27-12] (16 bits) | 3326 | Device ID |
Bit [11-0] (12 bits) | 1cf | IEEE 1149.1 Manufacturer ID for Actel |
