The status polling I/O
write is performed, reading is possible by enabling CE and OE.
Status read mode is used to identify what type of abnormal end has occurred. Use this mode when an abnormal end
occurs in auto-program mode or auto-erase mode.
The return code is retained until a command write for other than status read mode is performed.
