Figure 26.7
The port P4_i (i = 0 to 7) shares a pin with the serial interface (UART3 and UART6) and the intelligent I/O
group 2 (IIO2).
To use as an output pin, the PD4_i bit should be set to 1 (Port P4_i functions as output port) and a
function should be selected according to the Figure 26.7. To use as an input pin, the PD4_i bit should be
set to 0 (Port P4_i functions as input port).
Ports P4_0 to P4_7 are 5 V tolerant inputs. To use as an I/O pin with 5 V tolerant input enabled, the NOD
bit should be set to 1.
