Command Sequence:
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:
5.6.2.8.14 Reset Peripherals (RST). RST asserts RESET for 512 clock cycles. The CPU
is not reset by this command. This command is synonymous with the CPU RESET
instruction.
MOTOROLA
The 32-bit operand data is the starting location of the patch routine, which is the initial
PC upon exiting BDM.
None
