Alternate Port Functions
Most port pins have alternate functions in addition to being general digital I/Os.
shows how the port pin control signals from the simplified
alternate functions. The overriding signals may not be present in all port pins, but the figure
serves as a generic description applicable to all port pins in the AVR microcontroller family.

are not shown in the succeeding tables. The overriding signals are generated internally in
1. WRx, WPx, WDx, RRx, RPx, and RDx are common to all pins within the same port. clk
summarizes the function of the overriding signals. The pin and port indexes from
Pxn
SLEEP, and PUD are common to all ports. All other signals are unique for each pin.
