1.2.2 Part ID Assignments
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses 0x001A and 0x001B after
reset. The read-only value is a unique part ID for each revision of the chip. Table 1-2 shows the assigned
part ID numbers.

Bit 15–12: Major family identifier
Bit 11–8: Minor family identifier
Bit 7–4: Major mask set revision number including FAB transfers
Bit 3–0: Minor — non full — mask set revision
The device memory sizes are located in two 8-bit registers MEMSIZ0 and MEMSIZ1 (addresses 0x001C
and 0x001D after reset). Table 1-3 shows the read-only values of these registers. Refer to HCS12 Module
Mapping Control (MMC) block description chapter for further details.
