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 1-5 shows the assigned part ID
number and Mask Set number.
The Version ID in Table 1-5 is a word located in a flash information row at address 0x040B6. The version
ID number indicates a specific version of internal NVM controller.
