1.6 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.
Table 1-3 Assigned Part ID Numbers
1.7 Memory Size Assignments
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 HCS12 Module
Mapping Control (MMC) Block Guide for further details.
