RI (Return from Interrupt)
[Program Flow]
DESCRIPTION:
The RI command is used to end the interrupt subroutine beginning with the label #ININT . An RI (Return
from Interrupt) at the end of this routine causes a return to the main program. The RI command also
re-enables input interrupts. If the program sequencer was interrupted while waiting for a trippoint, such as
WT (Wait) , RI1 restores the trippoint upon return to the program. RI0 clears a trippoint. To avoid returning
after an interrupt, use the ZS (Zero Subroutine Stack) command to zero the subroutine stack. Check the
example section for more details about using interrupts.
ARGUMENTS: RI n where
n = 0 or 1
0 or nothing clears interrupt trippoint
1 restores trippoint
