Analog power-on sequence of A/D converter, D/A converter and comparator
The power to the A/D converter, D/A converter and comparator (AV
CC
, CV
CC
, AVR, CVRH1, CVRH2 and CVRL)
and analog inputs (AN0 to AN11, VOL1 to VOL3, VSI1 to VSI3, SW1 to SW3, DCIN and DCIN2) must be
turned on after the power to the digital circuits (V
CC
) is turned on. When turning off the power, turn off the
power to the digital circuits (V
CC
) after turning off the power to the A/D converter, D/A converter, comparator
and analog inputs. When the power is turned on or off, AVR should not exceed AV
CC
. And CVRH1, CVRH2
and CVRL should not exceed CV
CC
. Also, when a pin that is used for A/D analog input is used as an input port,
the input voltage should not exceed AV
CC
. And when comparator analog input is also used as an input port,
the input voltage should not exceed CV
CC
. (The power to the analog circuits and the power to the digital circuits
can be simultaneously turned on or off.)
Caution on Operations during PLL Clock Mode
If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even
when there is no external oscillator or external clock input is stopped. Performance of this operation, however,
cannot be guaranteed.
