40.4 Pin Name List
40.5 Product Dependencies
40.5.1 I/O Lines
The analog input pins (AD0-AD7 and DAC0-1) are multiplexed with PIO lines. In this case, the assignment of the ACC
inputs is automatically done as soon as the corresponding input is enabled by writing the ACC Mode register
(SELMINUS and SELPLUS).
40.5.2 Power Management
The ACC is clocked through the Power Management Controller (PMC), thus the programmer must first configure the
PMC to enable the Analog Comparator Controller clock.
Note that the voltage regulator needs to be activated to use the Analog Comparator.
40.5.3 Interrupt
The ACC has an interrupt line connected to the Interrupt Controller (IC). Handling the ACC interrupt requires
programming the Interrupt Controller before configuring the ACC.
40.5.4 Fault Output
The ACC has the FAULT output connected to the FAULT input of PWM. Please refer to chapter Section 40.6.5 ”Fault
Mode” and implementation of the PWM in the product.
