Power-on reset voltage (3 V)

<1> Apply supply voltage VDD.

<2> When VDD becomes higher than power-on reset voltage, device starts operating.

<3> Device stabilization time (less than 10 ms for internal oscillator)

During this time, do not execute STB pin input.

<4> After oscillation stabilization time is over, an STB signal input is waited for.

<5> When a logic high or logic low STB signal is input, a logic high is output from the BUSY pin, and a command input is waited for.

<6> A command input is waited for.

<7> When VDD becomes again a value lower than the power-on reset voltage, device operation stops.

<8> When VDD becomes again a value higher than the power-on reset voltage, device operation starts.

<9> Oscillation stabilization time (less than 10 ms for internal oscillator).

<10> After oscillation stabilization time is over, an STB signal input is waited for.

<11> When a logic high or logic low STB signal is input, a logic high is output from the BUSY pin, and a command input is waited for.

<12> A command input is waited for.
