9.12 Port E
9.12.1 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 on-chip MOS input pull-up function that can be controlled by software (on-chip ROM version only).
Figure 9-22 shows the port E pin configuration.
