4.2.2 DID1 Register (Offset = 0x4) [reset = X]
Device Identification 1 (DID1)
This register identifies the device family, part number, temperature range, pin count, and package type. Each microcontroller is uniquely identified by the combined values of the CLASS field in the DID0 register and the PARTNO field in the DID1 register.
DID1 is shown in Figure 4-8 and described in Table 4-12.
