1.7 Part ID Assignments
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses $001A and $001B after
reset). The read-only value is a unique part ID for each revision of the chip. Table 1-3 shows the assigned
part ID number.
The device memory sizes are located in two 8-bit registers MEMSIZ0 and MEMSIZ1 (addresses $001C
and $001D after reset). Table 1-4 shows the read-only values of these registers. Refer to section Module
Mapping and Control (MMC) of HCS12 Core User Guide for further details.
