8.2 Analog Connections
The analog peripherals can be connected to each other according to the block diagram above. To configure a particular peripheral refer to the corresponding description in this data sheet.
Peripherals can be connected through a pad. In this case, the digital functionality of the pad is lost and its configuration must not interfere with the analog connection.
Important:
When an analog peripheral is enabled, the analog output of the peripheral will interfere with the alternative functions of the output pads. This is also true even when the peripheral is used for internal purposes.
Analog inputs do not interfere with alternative pad functions.
