8.10
The port E is an 8-bit I/O port also functioning as data bus (D7 to D0) I/O pins. The port E has the
following registers.
• Port E data direction register (PEDDR)
• Port E data register (PEDR)
• Port E register (PORTE)
• Port E pull-up MOS control register (PEPCR)
8.10.1
PEDDR specifies input or output for the pins of the port E.
Since PEDDR is a write-only register, the bit manipulation instructions must not be used to write
PEDDR. For details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.

Modes 4 to 6:
When 8-bit bus mode is selected, port E functions as an
I/O port. 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.
When 16-bit bus mode is selected, the input/output
direction settings in PEDDR are ignored, and port E pins
automatically function as data input/output pins.
For details on 8-bit/16-bit bus mode, refer to section 6,
Bus Controller.
Mode 7:
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.
(H8S/2212 Group)
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.
