Simulator features UM0036

Create and load a stimuli file on page 206 to trigger a signal on an interrupt request pseudo
pin.
The IRQx pseudo pin corresponds to the interrupt request number x. Refer to the interrupt
mapping table in the datasheet for your simulated microcontroller, to find the interrupt
request number for the interrupt that you want to generate. As an example, Table 70
provides the interrupt mapping for the ST7LITE1xB family.
For example, for ST7LITE1B to generate an auto-reload timer counter 2 overflow interrupt,
you must change the value of pin IRQ13. If the interrupts are globally enabled, the program
will jump to the counter 2 overflow interrupt handler after the value on the interrupt pin has
changed (after execution of the current instruction, if the change is requested without delay).
