Analog-to-Digital Converter (S08ADC10V1)
14.6.1.2
In this example, the ADC module will be set up with interrupts enabled to perform a single 10-bit
conversion at low power with a long sample time on input channel 1, where the internal ADCK clock will
be derived from the bus clock divided by 1.
ADCCFG = 0x98 (%10011000)
ADCSC2 = 0x00 (%00000000)
ADCSC1 = 0x41 (%01000001)
ADCRH/L = 0xxx
data cannot be overwritten with data from the next conversion.
ADCCVH/L = 0xxx
APCTL1=0x02
APCTL2=0x00
