DMA Transfer
There are four ADC channel settings available. Once the input data of each channel reaches the
FIFO level, it is possible to read the data through the DMA path.
9.8.4
Sensor Wake-up
The DA16200 has an external sensor wake-up function that uses the analog input signal through an
Aux ADC. Even in Sleep mode 2/3, it detects the change of an external analog signal, wakes up from
Sleep mode 2/3, and converts the DA16200 into a normal operation. This function can be used in up
to four channels. Also, when multiple external sensors are used, analog signals are detected while
the channel are automatically changed. For example, if all four channels are set as input sources
which have their threshold register respectively, the channels are measured sequentially from 0 to 3.
If one of the four values exceed the allowed range of values set by the threshold register, the
DA16200 awakes from the Sleep mode 2/3. The value setting of the input change can be either over
threshold or under threshold.
