6.11.4.6 Continuous Scan Mode
NuMicro M051
In continuous scan mode, A/D conversion is performed sequentially on the specified channels
that enabled by CHEN bits in ADCHER register (maximum 8 channels for ADC). The operations
are as follows:
1. When the ADST bit in ADCR is set to 1 by software or external trigger input, A/D conversion
2. When A/D conversion for each enabled channel is completed, the result of each enabled
3. When all enabled channel sequentially completes A/D converting once, the ADF bit (ADSR[0])
4. Steps 2 to 3 are repeated as long as the ADST bit remains set to 1. When the ADST bit is
starts on the channel with the lowest number.
channel is stored in the A/D data register corresponding to each enabled channel.
will be set to 1. If the ADIE bit is set to 1 at this time, an ADINT interrupt is requested after A/D
conversion ends. Conversion of the 1st enabled channel starts again.
cleared to 0, A/D conversion stops and the A/D converter enters the idle state. When ADST is
cleared to 0, ADC controller will finish current conversion and the result of the lowest enabled
ADC channel will become unpredictable.
