5.16.4.4 Single-Cycle Scan Mode
In single-cycle scan mode, A/D conversion will sample and convert the specified channels once in
the sequence from the least to highest channel. Operations are as follows:
An example timing diagram for single-cycle scan on enabled channels (0, 2, 3 and 7) is shown as
below:
1.
2.
3.
4.
When the ADST bit in ADCR is set to 1 by a software or external trigger input, A/D
conversion starts on the channel with the lowest number.
When A/D conversion for each enabled channel is completed, the result is sequentially
transferred to the A/D data register corresponding to each channel.
When conversion of all the enabled channels is completed, the ADF bit in ADSR is set to
1. If the ADIE bit is set to 1 at this time, an ADC_INT interrupt is requested after A/D
conversion ends.
After A/D conversion ends, the ADST bit is automatically cleared to 0 and the A/D
converter enters idle state. If ADST is cleared to 0 before all enabled ADC channels
conversion done, ADC controller will finish current conversion and the result of the
lowest enabled ADC channel will become unpredictable.
