1. If connection of a resistor is specified and if it is specified that
the standby mode is released when this port goes low
... A pull-up resistor is connected. If a low level is input to
the set key, the standby mode is released.
2. If connection of a resistor is specified and if it is specified that
the standby mode is released when this port goes high
... A pull-down resistor is connected. If a high level is input
to the set key, the standby mode is released.
3. If connection of a resistor is not specified and if it is specified
that the standby mode is released when this port goes low
(or high)
... No resistor is connected. If a low (or high) level is input to
the set key, the standby mode is released.
If this port is set to the output mode when a key matrix is used, it
functions as an N-ch open-drain output port and can be used to
output key matrix signals.
If this port is set to the input mode when a key matrix is used, it
functions as a CMOS input port.
Connection of a resistor to this port and whether the resistor is
pull-up or pull-down can be selected in 1-bit units.
If this port is set in the output mode when a key matrix is not used,
it functions as a high-current CMOS output port.
