The CCRSAV register is used to save the CCR of the users program
when entering BDM. It is also used for temporary storage in the BDM
firmware.
Read and write: all modes
Hardware breakpoints are used to debug software on the
MC68HC912DT128A by comparing actual address and data values to
predetermined data in setup registers. A successful comparison will
place the CPU in background debug mode (BDM) or initiate a software
interrupt (SWI). Breakpoint features designed into the
MC68HC912DT128A include:
