Port F
Port F Input Pins Address –
PINF
0945I–AVR–02/07
Port F is an 8-bit input port.
One I/O memory location is allocated for Port F, the Port F Input Pins – PINF, $00 ($20).
All Port F pins are connected to the analog multiplexer, which further is connected to the
A/D converter. The digital input function of Port F can be used together with the A/D
converter, allowing the user to use some pins of Port F and digital inputs and other as
analog inputs, at the same time.
The Port F Input Pins address (PINF) is not a register; this address enables access to
the physical value on each Port F pin.
