Chapter 1 MC9S12HZ256 Device Overview

1.3 Part ID Assignments and Mask Set Numbers

The part ID is located in two 8-bit registers PARTIDH and PARTIDL at addresses 0x001A and 0X001B,

respectively. The rado-only value is a unique part ID for each revision of the chip. Table 1-6 shows the

assigned part ID and Mask Set numbers.

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 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 MEMZI1 (addresses 0x001C

and 0x001D after reset). Table 1-7 shows the read-only values of these registers. Refer to the HCS12 MMC

block description chapter for further details.
