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 Interrupt Controller.
Using the ADC interrupt requires the NVIC to be programmed first.
Table 39-2.
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 temperature sensor is connected to Channel 15 of the ADC.
The temperature sensor provides an output voltage V
ture (PTAT). To activate the temperature sensor, TSON bit (ADC_ACR) needs to be set.
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.
