Connects ceramic oscillator for system clock oscillation
4-bit CMOS input port with pull-up resistor.
Can be used for key return input of key matrix. When at least
one of these pins goes low, standby function is released.
4-bit input/output port.
Can be set in inputset in input or output mode in 1-bit units.
In output mode, this port functions as a highcurrent CMOS output
port. In input mode, function as CMOS input and can bespecified
to connect pull-up resistor by program.
4-bit N-ch open-drain output port.
Can be used for key source output of key matrix.
4-bit CMOS input port with pull-up resistor.
Can be used for key return input of key matrix. When at least
one of these pins goes low,standby function is released.
4-bit N-ch open-drain output port.
Can be used for key source output of key matrix.

Input
System reset input. CPU can be reset when low-level signal is
input to this pin. While low-level signal is input, oscillator circuit is
stopped. Can be connected to pull-upresistor by mask option.
Output detecting hang-up and drop in supply voltage.This pin
outputs at low level either when an overflow occurs in the
watchdog timer, when an overflow/underflow occurs in the stack,
or when the supply voltage drops below a specified level (mask
option). Connect this pin to the RESET pin.
