repeat(#3h)

data(0084h) = *AR7+ ; copy the NMI vector

AR7 = #00240h

repeat(#35)

data(00C0h) = *AR7+ ; copy INT0, INT1,

* initialize waitstates:

DP = #00000h ; point to page zero

IFR = #1 ; reset any old interrupt on pin INT0

@IMR | = #01 ; allow INT0

SXM=#0 ; no sign extension

* enable global interrupt (this is even required, if no IRQ routine is used

* by this program because the debugger needs to do its backgroud interrupts)

INTM = #0 ; enable global IRQ

*Setup up registers

Ready: BK=#21 ;circular addressing

AR7=#sinevals ;Point to sine table

DP=#sinevals ;point to correct Data Page

*Loop to repeatedly send Sine Wave

ReSend:

dgoto ReSend ;delayed goto (saves cycles)

port(#0)= *AR7+%
