Enable global interrupt enable
engint
Example: engint;
Result: Interrupt request can be sent to CPU
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Disable global interrupt enable
disgint
stopsys
stopexe
Example: disgint ;
Result: Interrupt request is blocked from CPU

System halt.
Example: stopsys;
Result: Stop the system clocks and halt the system
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
CPU halt. The oscillator module is still active to output clock, however, system clock is disabled
to save power.
Example: stopexe;
Result: Stop the system clocks and keep oscillator modules active.
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Reset the whole chip, its operation will be same as hardware reset.
Example: reset;
reset
Result: Reset the whole chip.
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
