I'm using AIO of CR1010 to read the voltage of the analog output sensor.
When AIO level is more than 1V, I observed the ripple voltage at AIO.
For example, when 1.2V is applied to AIO, the oscilloscope shows that
the voltage is 1V and sometimes goes up to 1.2V. The timing of 1.2V looks
like syncronizing with RF working.
Is there any ristriction to use AIO port of CR1010? I believe that I can apply
up to 1.35V to AIO port.
