Does the emulator system support execution of STP and WIT instructions?

Support conditions for STP and WIT instructions on the emulator system differ according to the program execution method.

Operation during Program Execution

When the STP or WIT instruction is executed while the user program is running, the clock stop operation and return to the

program from the clock stop state are in the same manner as with the MCU.

●

Operation during Single-Step or Over-Step Execution

When the STP or WIT instruction is executed in a single-step or over-step execution, the clock is stopped in the same manner

as with the MCU. Return to the program differs according to the following return triggers.

(1)Return due to Reset

The step operation is terminated (break) at the address set in the reset vector.

(2)Return due to Interrupt

After execution of an interrupt routine, the step operation is terminated (break) at the instruction following the STP or

WIT instruction. However, if the interrupt routine is an endless loop, a time out error will occur, because the interrupt

routine cannot terminate itself.
