Device Overview S12XS Family
Accessing the reserved area in the range of 0x0C00 to 0x0FFF will return undefined data values.
A CPU access to any unimplemented space causes an illegal address reset.
The range between 0x10_0000 and 0x13_FFFF is mapped to DFLASH (Data Flash). The DFLASH block
sizes are listed in
1.1.6
The detailed register map is listed in the appendix of the reference manual.
1.1.7
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses 0x001A and 0x001B).
The read-only value is a unique part ID for each revision of the chip.
number and Mask Set number.
The Version ID is a word located in a flash information row at 0x40_00E8. The version ID number
indicates a specific version of internal NVM variables used to patch NVM errata. The default is no patch
(0xFFFF).
