PROGRAM EXAMPLE

The following program enables interrupts and goes to a

routine to service it. Jumper H2[5-6]. Bringing P2-INT

to ground causes an inter rupt.

10 ONITR 0, 500

30 GOTO 30

500 PRINT "Got Interrupt"

510 RETI

Line 510 is necessary to re-enable interrupts. If this line

is not executed, but a RETURN is used, then the next

interrupt is disabled.
