Register Global Address 0x7FFF06
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 LOW holding register is used to save the low byte
of the condition code register of the user’s program. It is also used for temporary storage in the standard
BDM firmware mode. The BDM CCR LOW holding register can be written to modify the CCR value.
7.3.2.3
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.

When BDM is made active, the CPU stores the content of its CCR
in the BDMCCRL register. However, out of special single-chip reset, the
BDMCCRL is set to 0xD8 and not 0xD0 which is the reset value of the
CCR
BDMCCRL register is read zero.
