Reset input pin.
The LSI is initialized by the "L" level input. After a reset is input, all the
circuits stop operating and enter the power-down state.
At power-on, input an "L" level to this pin. After the power supply
voltage stabilizes, set this pin to an "H" level.
A pull-up resistor is internally connected to the LSI.
