CHAPTER 8: DEBUGGER

(S1C63 FAMILY ASSEMBLER PACKAGE)
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 ad-
dresses 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 <pass> <address1> [<address2> [<address3>]]↵ (direct input mode)
(2) >bs↵ (guidance mode)

Examples
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.

Number of seqential address (1-3) ? : 2↵ ... Number of addresses is input.
Set address ? : 116↵ ... 1st address is input.
Set address ? : 120↵ ... 2nd address is input.
Pass count ? : 3↵ ... Pass count is input.
