10-16. Software Reset

The Software Reset reset the device to the state just after power-on. This operation consists of two commands: the Reset

Enable (RSTEN) and the Reset command (RST).

"Figure 22. Software Reset" shows the timing waveforms.

The sequence of Software Reset operation :

CS goes to low  input RSTEN command (66h)

 CS goes to high

 CS goes to low  input RST command (99h)

 CS goes to high (be executed by the rising CS edge)

When the Software Reset is executed, an internal write (erase/program) operation is cancel, a suspended status is reset,

and all volatility status register bits (WEN/ RDY/SUS) are reset. After the internal reset time (tRST), the device will

become stand-by state. If the Software Reset is executed during a write (erase/program) operation, any dates on the write

operation will be broken.

The Reset command must input just after input the Reset Enable command. If another command input after the Reset

Enable command, the Reset-Enable state will be invalid.
