5.7.5 System Device Identiï¬cation Register (SDIDH, SDIDL)
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 speciï¬c memory blocks,
registers, and control bits are located in a target MCU.
