Description
Reads are undefined and writes have no effect.
Silicon version (revision) bits. These bits identify the silicon version of the device. Initial device
version numbers start at 0000. The current revision for the B512 device is 0010.
Technology family bit. 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 bit. This bit distinguishes between ROM and flash devices:
Flash device
ROM device
Device-specific part number bits. These bits identify the assigned device-specific part number. The
assigned device-specific part number for the B512 device is 0100101.
Mandatory High.
Bits 2, 1, and 0 are tied high by default.
