1.6 Part ID Assignments
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses 0x001A and 0x001B).
The read-only value is a unique part ID for each revision of the chip. Table 1-4 shows the assigned part ID
number and Mask Set number.
The Version ID in Table 1-4. is a word located in a flash information row at address 0x40_00E8. The
version ID number indicates a specific version of internal NVM controller.
