44.5.1 I/O Lines
The analog input pins (AD0-AD7 and DAC0-1) are multiplexed with digital functions (PIO) on the IO line. By writing
the SELMINUS and SELPLUS fields in the ACC Mode register (ACC_MR), the associated IO lines are set to
analog mode.

44.5.2 Power Management
The ACC is clocked through the Power Management Controller (PMC), thus the programmer must first configure
the PMC to enable the ACC clock.
the PMC to enable the ACC clock.
Note that the voltage regulator must be activated to use the analog comparator.
44.5.3 Interrupt
The ACC has an interrupt line connected to the Interrupt Controller (IC). In order to handle interrupts, the Interrupt
Controller must be programmed before configuring the ACC.
