Functional Description and Application Information
To avoid any critical behavior, it is essential to have the MCU Power On Reset (POR) active when the analog die reset
(RESET_A) is not fully active. As the RESET_A circuity is supplied by VDDX, VDD needs to be below the POR threshold when
VDDX is to low to guarantee RESET_A active (3;6). This is achieved with the following implementation.

The VDD regulator is enabled after VDDX has reached the V
Once VDD reaches V
Once VDDX has reached the V
pulled down to discharge any VDD capacitance (5). RESET_A is activated as well.
The active discharge guarantees VDD to be below POR level before VDDX discharges below critical level for the reset
circuity.
