(4) Sequential break (only in the ICE mode)
For sequential breaks, you can specify one to three addresses, data patterns, data masks, and bus operation
types. A break occurs when the program performs each specified type of bus operation in the order of
specified addresses.
Specify data patterns and masks in a 16-bit hexadecimal number.
Choose a bus operation type from the nine types listed below:
0. All
1. Inst
2. VecR
3. DatR
4. DatW
5. StkR
6. StkW
7. DmaR
8. DmaW
The sequential break function can only be used in ICE mode.
When this break occurs, the db33 displays the following message in the [Command] window and stands by
waiting for command input.
When using the bsq command, follow the guidance shown in the [Command] window as you enter the
break conditions.
Example:
No.
1
2
In this example, a break occurs when the CPU writes 1 to address 0xe00001 after executing the instruction
at address 0xc80000. The data mask 0xffff in No.1 specifies the mask in all the data pattern bits (the data
pattern is omitted from the break condition). The data mask 0xff00 in No.2 specifies that the low-order 8
bits of the data pattern is compared with the low-order 8 bits of the actual access data.

Command
This dialog box appears on the screen when you
select the [Sequential...] command from the
[Break] menu.
Enter an address, data pattern and data mask in
each text box and select a bus operation type from
the combo box, then click the [Add] button. The
entered break condition is set in order from Hit
No.1 to 3.
The address can also be specified using a symbol.
