The Input voltage on one pin selected by bits CH2 to CH0, and the
ADGSEL0 bit is comparator converted repeatedly
• When the ADCAP bit is set to 0 (software trigger),
set the ADST bit to 1 (comparator conversion starts).
• When the ADCAP bit is set to 1 (capture),
a timer Z interrupt request is generated while the ADST bit is set to 1.
Set the ADST bit to 0.
Not generated
Selects one of AN8 to AN11.
Read AD register.
