43.5 Product Dependencies

43.5.1 Power Management

The user must first enable the DAC Controller Clock in the Power Management Controller (PMC)

before using the DACC.

The DACC becomes active as soon as a conversion is requested and at least one channel is

enabled. The DACC is automatically deactivated when no channels are enabled.

For power-saving options, see Section 43.6.6 ”Sleep Mode”.

43.5.2 Interrupt Sources

The DACC interrupt line is connected to one of the internal sources of the interrupt controller. Using

the DACC interrupt requires the interrupt controller to be programmed first.

43.5.3 Conversion Performances

For performance and electrical characteristics of the DACC, see the DC Characteristics section of the

datasheet.
