SYStem.Option.IMASKASM

Disable interrupts while single stepping

Default: OFF.

If enabled, the interrupt mask bits of the CPU will be set during assembler single-step operations. The
interrupt routine is not executed during single-step operations. After single step the interrupt mask bits are
restored to the value before the step.
