1.3.3 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 1-7 shows the assigned
part ID number.

1_{The coding is as follows:}
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 1-8 shows the read-only values of these registers. Refer to HCS12 Module
Mapping and Control (MMC) block description chapter for further details.
