(CMOS/H)
General-purpose I/O port
This function is always valid.
Trigger input pin of the 8/10-bit A/D converter
Because this input is used as requited when the
8/10-bit A/D converter is performing input operations,
and it is necessary to stop outputs by other functions
unless such outputs are made intentionally.
I/O port of an open-drain type
The input function is valid when the analog input
enable register is set to select a port.

E
(CMOS/H)
General-purpose I/O port
This function is always valid.
Request input pins of the DTP/external interrupt
circuit
Because this input is used as required when the
DTP/external interrupt circuit is performing input
operations, and it is necessary to stop outputs from
other functions unless such outputs are made
intentionally.
General-purpose I/O port
This function is always valid.
Sample data input pins for ICU0 to ICU3
Because this input is used as required when the input
capture (ICU) is performing input operations, and it is
necessary to stop outputs from other functions unless
such outputs are made intentionally.
General-purpose I/O port
This function is valid when waveform output from the
output compare (OCU) is disabled.
Waveform output pins of OCU0 and OCU1
This function is valid when waveform output from
the output compare (OCU) is enabled and output
from the port is selected.
