EMI CONTROL
to the user to have the best efficiency by choosing the lowest value, or reduce the EMI perturbation by increasing it. By default
the programming value sets the fastest time to have the best efficiency.
HEADSET SUPPLY VOLTAGE AND LDO SETTING
internal converter set by the LDO control register.
The LDO control register bits (D3 to D0) set VRP and VRM.
The EMI control register sets the rising and falling edges of the Class D speaker outputs. This register gives the possibility
Apply a supply voltage from 1.6 V to 3.6 V to the pin HPV
