○Data is taken by DI sync with the rise of SK.
○At read action, data is output from DO in sync with the rise of SK.
○The status signal at write (READY / BUSY) is output after tCS from the fall of CS after write command input, at the area
○After completion of each mode execution, set CS “L” once for internal circuit reset, and execute the following action mode.
