Fault Output
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).
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.
The ACC has an interrupt line connected to the Interrupt Controller (IC). Handling the ACC inter-
rupt requires programming the Interrupt Controller before configuring the ACC.
Table 38-2.
The ACC has the FAULT output connected to the FAULT input of PWM. Please refer to chapter
