ST10F269 12 - PARALLEL PORTS
81/184
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 22 summarizes the alternate functions
of Port 5.
