6.7.1 Alternate functions of Port5
Each line of Port5 is also connected to the input multiplexer of the analog/digital converter.
All port lines (P5.15...P5.0) can accept analog signals (AN15...AN0) that can be converted
by the ADC. No special programming is required for pins that should be used as analog
inputs. The upper six pins of Port5 also serve as external timer control lines for GPT1 and
GPT2.
The Table 25 summarizes the alternate functions of Port5.
