12.8.1 - Alternate Functions of Port 5

Each line of Port 5 is also connected to one of the

multiplexer of the Analog/Digital Converter. All

port lines (P5.15...P5.0) can accept analog

signals (AN15...AN0) to be converted by the ADC.

No special programming is required for pins that

shall be used as analog inputs. Some pins of Port

5 also serve as external timer control lines for

GPT1 and GPT2.

The Table 18 summarizes the alternate functions

of Port 5.
