RETI
Syntax: RETI
Function: Return from ONITR or ONTICK interrupt. RETI must be the last instruction of the interrupt
subroutine.
Mode: Run
Use: RETI
DESCRIPTION
The RETI instruction causes you to exit from ONTICK and ONITR (if available) interrupts. RETI functions
like RETURN, but it clears software interrupt flags so that BASIC-52 can acknowledge subsequent
interrupts. If you don't execute the RETI instruction in the interrupt procedure, all future interrupts, hardware
and software, are ignored.
