Port E Data Direction Register (PEDDR)
PEDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port E. PEDDR cannot be read; if it is, an undefined value will be read.
PEDDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state by
a manual reset or in software standby mode.
• Modes 4 to 6
• Mode 7

Bit
Initial value :
R/W
When 8-bit bus mode has been selected, port E pins function as I/O ports. 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 has been selected, the input/output direction specification by PEDDR is
ignored, and port E is designated for data I/O.
For details of 8-bit and 16-bit bus modes, see section 7, Bus Controller.
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.
