PDOWN
Complete power-down can be controlled using the PDWN pin. ADC, PLL and other items can be powered down
individually by means of register settings. This makes it possible to limit the power consumption as required.

Item
ADC
Power-down can be controlled using dedicated registers. See below for the relevant registers.
PLL
Power-down can be controlled using dedicated registers. See below for the relevant registers.
Logic
External input is selected and the external clock is stopped.
Similarly, the clock is stopped by selecting the PLL mode and power down the PLL circuit.
Output pin
Output-enable (Hi-Z) can be set by using the dedicated registers.
Communication
Cannot be stopped.
