Refer toChapter 8, Interrupt Control, for more information on programming the interrupt controlmodule. To use interrupts, refer to section 3.6.5, Primary Analog Output Group-RelatedInterrupts.3.6.1.12 ArmingUse this function to arm the analog output counters and to preload the DACs with the firstanalog output value.Function AO_Arming{Begin critical section;AO_Not_An_UPDATE = 1;
