6.6.3 System Device Identification Register: High (SYS_SDIDH)
This read-only register, together with SYS_SDIDL, is included so that 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.

Part Identification Number
These bits, together with the SYS_SDIDL, indicate part identification number. Each derivative in the
HCS08 family has a unique identification number. This device is hard coded to the value .
6.6.4 System Device Identification Register: Low (SYS_SDIDL)
This read-only register, together with SYS_SDIDH, 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.
