If the JTAG interface is connected into the fuse bits of the microcontroller, then terminals PF4...PF7
(ADC4...ADC7) can serve only as an interface and cannot operate as I/O terminals or analogue inputs.
The programmer/emulator JTAG can be found on the page:

5 An application example
The diagram below shows the MMnet102 module in a simple application, controlling relays through the
Ethernet network (e.g. surfing the WWW). The diagram does not include the supply of power.
