General-purpose I/O port
This function is always valid.
DTP/external interrupt input pin
When external interrupts are enabled, these inputs may be
used at any time; therefore, it is necessary to stop output by
other functions on this pin, except when using them for output
deliberately.
General-purpose I/O port
This function is always valid.
DTP/external interrupt input pin
When external interrupts are enabled, these inputs may be
used at any time; therefore, it is necessary to stop output by
other functions on this pin, except when using them for output
deliberately.
Because an input to this pin is clamped to Low when the CPU
stops, use INT0 or INT1 to wake up the system from the stop
mode.
8/10-bit A/D converter trigger input pin
When 8/10-bit A/D converter is waiting for activation, this input
may be used at any time; therefore, it is necessary to stop
output by other functions on this pin, except when using it for
output deliberately.
CLK output pin

This function is valid in the flash memory mode.
