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 numbers.

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 Module Mapping

and Control (MMC) Block Guide for further details.
