5.16.4.3 Single Mode
In single mode, A/D conversion is performed only once on the specified single channel. The
operations are as follows:
Note: If software enables more than one channel in single mode, the channel with the lowest number will be
selected and the other enabled channels will be ignored.

NuMicro™ NUC130/NUC140 Technical Reference Manual
A/D conversion will be started when the ADST bit of ADCR is set to 1 by software or
external trigger input.
When A/D conversion is finished, the result is stored in the A/D data register
corresponding to the channel.
The ADF bit of ADSR register will be set to 1. If the ADIE bit of ADCR register is set to 1,
the ADC interrupt will be asserted.
The ADST bit remains 1 during A/D conversion. When A/D conversion ends, the ADST
bit is automatically cleared to 0 and the A/D converter enters idle state. Note that, after
clearing the ADST bit, the ADST bit must be kept at 0 at least one ADC clock period
before setting it to 1 again. If not, the A/D converter may not work.
