bs (sequential break)

Function

This command sets and clears sequential break and displays the sequential break condition that have been set.

This command allows you to set break addresses in up to three locations and the number of times you want the program to be executed at the last of the three addresses. While passing through all addresses sequentially in the order they are set, the program executes the last-specified address a specified number of times, then breaks after fetching the instruction from that address again.

Format (1)

 

 

 

 

>bs 3 116 120↵

 

 

 

 

... Sets two sequential addresses and the pass count. In this case, a break will occur when the

 

CPU fetches the instruction at address 0x0120 after the instruction at address 0x0116 is executed

 

and the instruction at address 0x0120 is executed three times.
