3.3.2 Breakpoints and Swi Instruction
The HC08’s on-chip debug module only handles one hardware breakpoint.
However, you can force the program execution to stop at other specific
locations by inserting the “swi” Assembly instruction on your source code.
3.3.3 Reading Peripheral Status
Care must be taken when reading some peripheral’s status/data registers,
since a reading operation may cause the clearing of flags. This may happen
when the “Memory” window or the “Data” window is open, since these
windows read microcontroller’s resources during refresh operations.
3.3.4 Interrupt Execution during Steps
When issuing stepping instructions (Single Step, Step Over, etc.) and there
are pending interrupts, inDART-One will not step inside the interrupt
handling routine, but the whole interrupt handling routine is executed. An
exception is when you single step on an Assembly instruction which
branches to itself: in this case, interrupts which may occur are not handled.
3.3.5 Peripheral Status during Steps
When single stepping on an Assembly instruction which branches to itself,
peripheral status is frozen.
The IRQ interrupt vector must be handled;
The IRQ handling routine must include the following code:
Under these conditions, the TGT_IRQ# line is reserved; when it is
driven low, a “Halt” debugging command is automatically recognized.

; Waits for the IRQ signal to go high
; Jumps to monitor code
