Miscellaneous Features->Trap Delayed Interrupts
Use this option to enable and disable the trapping of overlapping interrupts.
A warning will be given when this option is enabled and an interrupt routine cannot immediatley execute because another interrupt is already executing.
This option is enabled by default.
This warning is not given if an interrupt is delayed because the EA bit is clear and it is not given if the interrupt is of the same type as the interrupt that is running (eg. if a timer 1 overflow interrupt is active, a second timer 1 overflow interrupt will not be trapped).
A tick next to the item in the menu indicates that overlapping interrupts will be trapped.
