be individualy scheduled for conversion N times for when N samples are required before
an interrupt is generated. This is most easily accomplished by using one of the LRADC
Delay Channels.
EXAMPLE
if (HW_LRADC_CHn(6).TOGGLE == 1) { } // Toggle is high.
// ...
unsigned long channelAverage;
HW_LRADC_CHn_WR(6, (BF_LRADC_CHn_ACCUMULATE(1)
// ... setup Delay channel (see HW_LRADC_DELAY0 through 3)
while (HW_LRADC_CTRL1.LRADC6_IRQ != BV_LRADC_CTRL1_LRADC6_IRQ__PENDING)
{
}
channelAverage = HW_LRADC_CHn(6).VALUE / 5;
