15.3.2.3
Register Global Address 0x7FFF07
Read: All modes through BDM operation when not secured
Write: All modes through BDM operation when not secured
When entering background debug mode, the BDM CCR HIGH holding register is used to save the high
byte of the condition code register of the user’s program. The BDM CCR HIGH holding register can be
written to modify the CCR value.
15.3.2.4
Register Global Address 0x7FFF08
Read: All modes through BDM operation when not secured
Write: All modes through BDM operation when not secured
15.3.3
The family ID is a 8-bit value located in the firmware ROM (at global address: 0x7FFF0F). The read-only
value is a unique family ID which is 0xC1 for S12X devices.

Family ID Assignment
BDM Global Page Access Enable Bit — BGAE enables global page access for BDM hardware and firmware
read/write instructions The BDM hardware commands used to access the BDM registers (READ_BD_ and
WRITE_BD_) can not be used for global accesses even if the BGAE bit is set.
0 BDM Global Access disabled
1 BDM Global Access enabled
BDM Global Page Index Bits 6–0 — These bits define the extended address bits from 22 to 16. For more
detailed information regarding the global page window scheme, please refer to the S12X_MMC Block Guide.
