that the conversion is completed or wait until the interrupt signal (INTADC) is generated (e.g., interrupt han-
dling routine).
When ADCCR1<ADRS> is set to "1", AD conversion of the voltage at the analog input pin specified by
After completion of the AD conversion, the conversion result is stored in AD converted value registers
ADCCR1<ADRS> is automatically cleared after AD conversion has started. Do not set ADCCR1<ADRS>
1. Set up the AD converter control register 1 (ADCCR1) as follows:
2. Set up the AD converter control register 2 (ADCCR2) as follows:
3. After setting up 1. and 2. above, set AD conversion start (ADRS) of AD converter control register 1
