Reset is applied and the base clock is stopped. However, the OSC pin state (normal or sleep mode)
is determined after the S0 and S1 control data bits are transferred.
Reset is applied and the display is turned off. However, display data can be input to the latch circuit
in this state.
Reset is applied, the circuit is set to the initial state, and at the same time the key scan operation is
disabled.
Reset is applied and all the key data is set to low.
Since serial data transfer is possible, these circuits are not reset.
