User Application Note
(Before using this chip, take a look at the following description note, it includes important messages.)
1. The internal TCC will stop running when in sleep mode. However, during AD conversion, when
TCC is set to “SLEP” instruction, if the ADWE bit of the RE register is enabled, the TCC will keep
on running.
2. During ADC conversion, do not perform output instruction to maintain precision for all of the pins.
In order to obtain accurate values, it is necessary to avoid any data transition on I/O pins during
AD conversion
3. The noise rejection function is turned off in the Fs and sleep mode
