A
device identification code register
The device identification code register identifies the silicon version, the technology family (TF), a ROM or Flash
device, and an assigned device-specific part number (see Figure 3). The A64 device identification code register
value is 0x083F.

VERSION
Reads are undefined and writes have no effect.
Silicon version (revision)
These bits identify the silicon version of the device.
Technology Family
This bit distinguishes the technology family core power supply:
3.3 V for F10/C10 devices
1.8 V for F05/C05 devices
ROM/Flash
This bit distinguishes between ROM and Flash devices:
Flash device
ROM device
Device-specific part number
These bits identify the assigned device-specific part number. The assigned device-specific
part number for the A64 device is 0000111.
