Register Map
All registers are initialized to their default values by setting the PDN1 and PDN2 pins to “L”.
ADC is powered down by setting the PDN1 pin to “L”. Registers for ADC (Addr: 01h-02h) and PWAD bit are
initialized.
DAC is powered down by setting the PDN2 pin to “L”. Registers for DAC (Addr: 03h) and PWDA bit are
initialized.
ADC is powered down by setting the PWAD bit to “0”. However, registers for ADC (Addr: 01h-02h) are not
initialized.
DAC is powered down by setting the PWDA bit to “0”. However, registers for DAC (Addr: 03h) is not initialized.
The bits defined as 0 must contain a “0” value.
