System Device Identication Register (SDIDH, SDIDL)
These high page read-only registers are included so host development systems can identify the HCS08
derivative and revision number. This allows the development software to recognize where specic memory
blocks, registers, and control bits are located in a target MCU.

Description
7
Bit 7 will read as a 1 for the MC9S08SG8 Series devices; writes have no effect.
6:4
Reserved
Bits 6:4 are reserved. Reading these bits will result in an indeterminate value; writes have no effect.
3:0
ID[11:8]
Part Identication Number — Each derivative in the HCS08 Family has a unique identication number. The
MC9S08SG8 is hard coded to the value 0x014. See also ID bits in Table 5-8.
