○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.
DO where CS is “H”, and valid until the next command start bit is input. And, white CS is “L”, DO becomes High-Z.
