4.5 Settings of Port Related Register When Using Alternate Function

To use the alternate function of a port pin, set the port mode register, and output latch as shown in Table 4-12.

Caution If the output function of an alternate function is assigned to a pin that is also used as an output pin,

the output of the unused alternate function must be set to its initial state. See 4.6.2 for details about

the applicable units and how to handle such pins.

Table 4-12. Settings of Port Related Register When Using Alternate Function (1/2)

ANI4 to ANI7

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.
