Conversion Performances
The MCK of the ADC Controller is not continuously clocked. The programmer must first enable
the ADC Controller MCK in the Power Management Controller (PMC) before using the ADC
Controller. However, if the application does not require ADC operations, the ADC Controller
clock can be stopped when not needed and restarted when necessary. Configuring the ADC
Controller does not require the ADC Controller clock to be enabled.
The ADC interrupt line is connected on one of the internal sources of the Advanced Interrupt
Controller. Using the ADC interrupt requires the NVIC to be programmed first.
Table 42-2.
The analog input pins can be multiplexed with PIO lines. In this case, the assignment of the ADC
input is automatically done as soon as the corresponding channel is enabled by writing the reg-
ister ADC_CHER. By default, after reset, the PIO line is configured as input with its pull-up
enabled and the ADC input is connected to the GND.
The pin ADTRG may be shared with other peripheral functions through the PIO Controller. In
this case, the PIO Controller should be set accordingly to assign the pin ADTRG to the ADC
function.
Timer Counters may or may not be used as hardware triggers depending on user requirements.
Thus, some or all of the timer counters may be non-connected.
PWM Event Lines may or may not be used as hardware triggers depending on user
requirements.
For performance and electrical characteristics of the ADC, see the DC Characteristics section.
