Figure 9.20 Port E Pin Functions (Modes 4 to 6)
Mode 7: In mode 7, port E pins function as I/O ports. Input or output can be specified for each pin
on a bit-by-bit basis. Setting a PEDDR bit to 1 makes the corresponding port E pin an output port,
while clearing the bit to 0 makes the pin an input port.
Port E pin functions in mode 7 are shown in figure 9.21.
