41.4 Pin Name List
41.5 Product Dependencies
41.5.1 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.
41.5.2 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.
Note that the voltage regulator must be activated to use the analog comparator.
41.5.3 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.
41.5.4 Fault Output
The ACC has the FAULT output connected to the FAULT input of PWM. Please refer to chapter Section 41.6.4 ”Fault
Mode” and implementation of the PWM in the product.
