Reset input pin. When this pin is set to a “L” level, system reset mode is
set and the internal section is initialized. When this pin is set to a “H” level
subsequently, program execution starts. A pull-up resistor is internally
connected.
Crystal connection pin for low-speed clock.
A 32.768 kHz crystal oscillator (see measuring circuit 1) is connected to
this pin. Capacitors CDL and CGL are connected across this pin and V
as required.
Crystal/ceramic connection pin for high-speed clock.
A crystal or ceramic is connected to this pin (4.1 MHz max.). Capacitors
CDH and CGH (see measuring circuit 1) are connected across this pin
and V
This pin is used as the secondary function of the P10 pin(OSC0) and P11
pin(OSC1).
Low-speed clock output pin. This pin is used as the secondary function of
the P20 pin.
High-speed clock output pin. This pin is used as the secondary function of
the P21 pin.
General-purpose input port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
General-purpose input port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
These pins are for the ML610Q429, but are not provided in the
ML610Q428.
General-purpose input port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
General-purpose output port.
Since these pins have secondary functions, the pins cannot be used as a
port when the secondary functions are used.
Since these pins have secondary functions, the pins cannot be used as a
