8.6 Device Identification
8.6.1 Device Identification Code Register
The device identification code register identifies several aspects of the device including the silicon version.
The details of the device identification code register are shown in Table 8-2. The device identification code
register value for this device is:
• Rev A = 0x8046AD05
• Rev B = 0x8046AD15
• Rev C = 0x8046AD1D
