Notes on Commands for Executing Program

When using commands to execute a program, there are several points to note.

Notes on GO Command

For the GO command, two breakpoints that are valid only while executing commands can be set. However, it

is required to be careful in setting these breakpoints.

- Invalid Breakpoints

No break occurs when a breakpoint is set at the instruction immediately after the following instructions.

- No break occurs when breakpoint set at address other than starting address of instruction.

- No break occurs when both following conditions met at one time.

- Instruction for which breakpoint set starts from odd-address,

- Preceding instruction longer than 2 bytes length, and breakpoint already set at last 1-byte address of

preceding instruction (This "already-set" breakpoint is an invalid breakpoint that won't break, because

it has been set at an address other than the starting address of an instruction).
