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
MC68HC912D60A 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
MC68HC912D60A include:
•
•
•
•
•
•
•
•
Mode selection for BDM or SWI generation
Program fetch tagging for cycle of execution breakpoint
Second address compare in dual address modes
Range compare by disable of low byte address
Data compare in full feature mode for non-tagged breakpoint
Byte masking for high/low byte data compares
R/W compare for non-tagged compares
Tag inhibit on BDM TRACE
