Table 113. Pins controlled by the ENAIO0 register
By default, all pins are connected to their digital function 0 and the corresponding ENAIO0
register bit is set to one. In this case, only the digital pad is available.
Before selecting the analog pad by setting the ENAIO0 register bit to zero, the digital pad
must be set as follows using the corresponding SFSP register:
