As shown in Figure 32, a typical application case includes a host processor, a Main PMIC (for

example, DA9063) and DA9211 or DA9212 used as companion IC for the high power core supply.

The easiest way of controlling DA9211 and DA9212 is through the Control Interface. The master

initiating the communication must always be the host processor that reads and writes to the main

PMIC, and to the DA9211 and DA9212 registers. To poll the status of DA9211 or DA9212, the host

processor must access the dedicated register area through the Control Interface. DA9211 and

DA9212 can be additionally controlled by means of hardware inputs.
