3.11 Device Identification Code Register
The device identification code register identifies the coprocessor status, an assigned device-specific part
number, the technology family (TF), the I/O voltage, whether or not parity is supported, the levels of flash
and RAM error detection, and the device version. The TMS470M device identification code base register
value is 0X00366D05 and is subject to change based on the silicon version.
