Figure 8.21 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 PEDDR bits to 1 makes the corresponding port E pins output
ports, while clearing the bits to 0 makes the pins input ports.
Port E pin functions in mode 7 are shown in figure 8.22.
