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) that can 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 below summarizes the alternate functions of Port 5.
