13.4.5 Analog function select register
Table 116. ADC1 function select register (ENAIO1, address 0x4008 6C8C) bit description
For pins which have digital and analog functions, this register selects the analog DAC and
band gap function over any of the possible digital functions.
In addition, the DAC function is pinned out on a dedicated analog pin which is not affected
by this register.
The following pins are controlled by the ENAIO1 register:
Table 117. Pins controlled by the ENAIO2 register
By default, all pins are connected to their digital function 0 and the corresponding ENAIO2
register bit is set to one. In this case, only the digital pad is available.
Before selecting the analog pad by setting the ENAIO2 register bit to zero, the digital pad
must be set as follows using the corresponding SFSP register:
