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 (H8S/2351
only).
Figure 9.22 shows the port E pin configuration.
Note: * Modes 2, 3, 6, and 7 only apply to the H8S/2351.
