RETI

Syntax: RETI

Function: Return from ONITR or ONTICK interrupt. RETI must be the last instruction of the interrupt

subroutine.

DESCRI PTION

The R ETI in struction causes you to exit from O NTICK , ONT IME (RPC -52 ca rd only ) and ONITR inte rrupts.

RETI functions like RETURN, but it clears software interrupt flags so that RPBASIC-52 can acknowledge

subsequent interrupts. If you don't execute the RETI instruction in the interrupt proc edure, all future

interrupts, hardware and software, are ignored.

ONITR, ONTICK

EXAMPLE

Refer to ONTICK and ONITR examples.
