12.7 - Port 5
This 16-bit input port can only read data. There is no output latch and no direction register. Data written to
P5 will be lost.
P5 (FFA2h / D1h)
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 pro-
gramming is required for pins that shall be used as analog inputs. Some pins of Port 5 also serve as exter-
nal timer control lines for GPT1 and GPT2. The table below summarizes the alternate functions of Port 5.
