bsq (break sequential)
This command sets, clears, and displays a sequential break.
Up to three combinations of an address, data pattern, data mask and bus operation type can be set. A break occurs
when the CPU executes a bus operation that satisfies the set conditions in the order these conditions are set.
(1) bsq
(2) bsq <mode> <hit> [<condition1> [<condition2> [<condition3>]]] (direct input mode)

Input examples
<mode>:
<hit>:
<condition>: Break condition (<address> <data> <mask> <bus type>)
Condition:
Format 1 displays the contents of current settings.
Shown above is an example where conditions 1 and 2 are set. The asterisks "****" in condition 3 indicate
that no condition has been set. The data mask "0000" indicates that the specified data pattern bits will all be
compared. In this example, a break occurs when the CPU fetches instruction code 0x6c00 from address
0xc80000 and then instruction code 0x6c11 from address 0xc80002. When the CPU accesses the addresses
in the retrograde order or only condition 2 is met, no break occurs.
Set/clear specification (1=set, 2=clear)
Sequence specification (1=Hit 1 only, 2=Hits 1 and 2, 3: Hits 1 to 3)
<address>: Address (hexadecimal, symbol or line number)
<data>:
<mask>:
<bus type>: Bus operation type (decimal number from 0 to 8)
0
address
Data pattern (16-bit hexadecimal number to be compared.)
Data mask (16-bit hexadecimal number for masking the data bits.)
Bits set at "0" specify the data bit to be compared, and bits set at "1" specify the
data bits to be masked.
0: All
1: Inst
2: VecR
3: DatR
4: DatW
5: StkR
6: StkW
7: DmaR
8: DmaW
