The Input voltage on one pin selected by CH2 to CH0 and ADGSEL0 bits
is A/D converted repeatedly
• When the ADCAP bit is set to 0 (software trigger)
• When the ADCAP bit is set to 1 (starts in timer RD (complementary PWM

Set the ADST bit to 1 (A/D conversion starts)
The compare match in the TRD0 and TRDGRA0 registers or the TRD1
underflow is generated while the ADST bit is set to 1
