3.12 GO EXECUTE USER PROGRAM
GO [<addr>]
Use the GO command (alias G) to initiate target code execution. All previously set breakpoints
are enabled. If an address is specified, it is placed in the target PC. Execution starts at the target
PC address.
The sequence of events is:
1. An address is specified and loaded into the target PC
2. If a breakpoint is set at the target PC address, the instruction is traced at the target PC
(executed in trace mode)
3. All breakpoints are inserted in the target code
4. Target code execution resumes at the target PC address
There are several methods for returning control to CPU32Bug:
Execute the .RETURN TRAP #15 function
Press the ABORT switch or RESET switch of the M68300PFB Platform Board
Encountering a breakpoint with 0 count
Generation of an unexpected exception
