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 Table 7). The VF3x6A device identification code
register value is 0x983F.
Table 7. TMS470 Device ID Bit Allocation Register
LEGEND:
For bits 3–15:
R = Read only, -K = Value constant after RESET
For bits 0–2:
R = Read only, -1 = Value after RESET
Bits 31:16
Reserved. Reads are undefined and writes have no effect.
Bits 15:12
VERSION. Silicon version (revision) bits
These bits identify the silicon version of the device.
Bit 11
TF. Technology Family (TF) bit
This bit distinguishes the technology family core power supply:
0 = 3.3 V for F10/C10 devices
1 = 1.8 V for F05/C05 devices
Bit 10
R/F. ROM/flash bit
This bit distinguishes between ROM and flash devices:
0 = Flash device
1= ROM device
Bits 9:3
PART NUMBER. Device-specific part number bits
These bits identify the assigned device-specific part number.
The assigned device-specific part number for the VF3x6A device is: 0000111.
Bits 2:0
"1" Mandatory High. Bits 2,1, and 0 are tied high by default.
