WPx, WDx, RRx, RPx, and RDx are common to all pins within the same port. clk I/O , SLEEP,and PUD are common to all ports. All other signals are unique for each pin.Table 12-2 summarizes the function of the overriding signals. The pin and port indexes from Figure12-5 are not shown in the succeeding tables. The overriding signals are generated internallyin the modules having the alternate function.8155C–AVR–02/1156
