Note: 1. WEx, WRx, WPx, WDx, REx, RRx, RPx, and RDx are common to all pins within the same port. clk_I/O, and SLEEP
are common to all ports. All other signals are unique for each pin.
The illustration in the figure above serves as a generic description applicable to all port pins in the AVR microcon-
troller family. Some overriding signals may not be present in all port pins.
