P0D2
In the input mode, these pins serve as CMOS input pins with a

P0D3
pull-up resistor, and can be used to input the key return signals of
a key matrix. The standby status must be released when at least
one of the input lines goes low. In the output mode, these pins are
used as N-ch open-drain output pins and can be used to output
the signals of a key matrix.

(whether it is released when this pin is high or low) can be
selected.
1. If connection of a resistor is specified and if it is specified that
the standby mode is released when this pin goes low
... A pull-up resistor is connected. If a low level is input to the
P1B0 pin, 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 pin goes high
... A pull-down resistor is connected. If a high level is input to
the P1B0 pin, 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 pin goes low
(or high)
... No resistor is connected. If a low (or high) level is input to
the P1B0 pin, the standby mode is released.
If a key matrix is not used, whether a resistor is connected and
whether the resistor is pull-up or pull-down can be
selected.
INT
This is an external interrupt request signal. It can also be used
to release the standby mode if an external interrupt request
signal is input to this pin while the INT pin interrupt enable flag
(IP) is set.
