Overview
Port E is an 8-bit I/O port. Port E has a data bus I/O function, and the pin functions change
according to the operating mode and whether 8-bit or 16-bit bus mode is selected.
Port E has a built-in MOS input pull-up function that can be controlled by software.
Figure 10-19 shows the port E pin configuration.
