Figure 14-5. Alternate port functions
Note:
1. WRx, 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 14-2 on page 67 summarizes the function of the overriding signals. The pin and port indexes from Figure 14-
5 on page 66 are not shown in the succeeding tables. The overriding signals are generated internally in the mod-
ules having the alternate function.
