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.
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.
NOTES:
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
2. 1L86D is identical to 2L86D except improved ESD performance on 2L86D
