5.8.5
This read-only register is included so host development systems can identify the HCS08 derivative and
revision number. This allows the development software to recognize where specific memory blocks,
registers, and control bits are located in a target MCU.
Freescale Semiconductor
The revision number that is hard coded into these bits reflects the current silicon revision level.

Revision Number — The high-order 4 bits of address 0x1806 are hard coded to reflect the current mask set
revision number (0–F).
Part Identification Number — Each derivative in the HCS08 Family has a unique identification number. The
MC9S08GBxxA/GTxxA is hard coded to the value 0x002. See also ID bits in
