Operand Data:
Result Data:
As an example, consider the following code segment. It outputs a character from the
MC68340 serial module channel A.
BDM and the CALL command can be used to patch the code as follows:
5-78

The 32-bit operand data is the starting location of the patch routine, which is the initial PC
upon exiting BDM.

If a bus error or address error occurs during return address
stacking, the CPU returns an error status via the serial interface
and remains in BDM.
If a bus error or address error occurs on the first instruction
prefetch from the new PC, the processor exits BDM and the er-
ror is trapped as a normal mode exception. The stacked value of
the current PC may not be valid in this case, depending on the
state of the machine prior to entering BDM. For address error,
the PC does not reflect the true return PC. Instead, the stacked
fault address is the (odd) return PC.
