Are there any ways to reduce the MCU's current consumption when using A/D conversion? [2009/08/05]
The following methods are available.
Please perform A/D conversion only when sampling is necessary. Also, when not performing A/D conversion, make sure to disconnect the resistor ladder from the reference voltage input pin (VREF) by setting 0 (automatic) to the VREF input switch bit.
In addition, when using wait mode or stop mode, please make sure to set as below:
- A/D input pin: Fix the A/D input pin to High or Low externally
- Complete an A/D conversion
(Confirm that the A/D conversion completion bit is set to 1.)
