46.4 Signal Description
46.5 Product Dependencies
46.5.1 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 46.6.6 ”DACC Timings”.
46.5.2 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.
46.5.3 Conversion Performances
For performance and electrical characteristics of the DACC, see the product DC Characteristics section of the
datasheet.
