2. The relationship between pins and their alternate functions shown in this table indicates the relationship
when a 32-pin product is used. In other products, alternate functions might be assigned to different pins,
but even in this case, the PMxx and Pxx set in the same way.
Note The functions of the ANI0/P20 to ANI7/P27 pins can be selected by using the A/D port configuration register
(ADPC), analog input channel specification register (ADS), and port mode register 2 (PM2).
