Interrupt Simulation

This section describes interrupt simulation executed.

■ Interrupt Simulation

This simulates the MCU operation for an interrupt request. The following types can be used to allow an

interrupt to occur.

•

When the instruction is executed as many cycles as the specified cycle count while executing a program
(executing execution commands), generate an interrupt corresponding to the specified interrupt number
to reset the interrupt generating condition.

•

Whenever the instruction executing cycle count exceeds the specified cycle, an interrupt continues to be
generated.

The type of interrupt can be set using either the [Setup] - [Debug Environment] - [Interrupt] menu, or the

SET INTERRUPT command in the Command window. If an interrupt is masked by an interrupt-enabled

flag when the interrupt generating condition is met, the interrupt is generated after resetting the mask.

When an interrupt is generated while executing a program, an interrupt cause number is displayed on the

Status Bar.

Furthermore, the simulator supports the MCU operation for interrupt requests for the following exception

processing.

•

Executing undefined instruction
