Setup Procedure Example
Follow the procedure below to set up the 10-bit A/D converter:
Initialization
1) Set the port for input (DDR1).
2) Set the interrupt level (ILR4).
3) Enable A/D input (ADC1:ANS0 to ANS3).
4) Set the sampling time (ADC2:TIM1, TIM0).
5) Select the clock (ADC2:CKDIV1, CKDIV0).
6) Set A/D conversion properties (ADC2:AD8).
7) Select the operation mode (ADC2:EXT).
8) Select the startup trigger (ADC2:ADCK).
9) Enable interrupts (ADC2:ADIE=1).
10)Activate A/D (ADC1:AD=1).
Interrupt processing
1) Clear the interrupt request flag (ADC1:ADI=0).
2) Read converted values (ADDH, ADDL)
3) Activate A/D (ADC1:AD=1).
