This function returns immediately and a separate notification informs the debugger that the execution state has changed. Typically this call results in the
modeChange() callback (if enabled) for
CADI_EXECMODE_Run followed by
virtual CADIReturn_t CADI::CADIExecSingleStep(uint32_t instructionCount, int8_t stepCycle, int8_t stepOver) = 0;
is the number of instructions to be executed.
Some targets can not step a specific number of instructions safely (into a delay slot, for example). In this case, the target can step additional instructions to enable it to stop at a safe place.
specifies (for targets that have exposed multiple
pipe stages) whether the step merely clocks the device (
yes) or flushes the pipe (
stepCycle == no).
For other kinds of targets, this argument is ignored (
no is assumed).
enables the target to handle stepping over a call.
It is especially useful for an emulator with no available breakpoints. In this case the target must step until the call returns or a breakpoint is hit.
