<Additional Information>
Clock input mode supports 2 types and data output timing changes as below accordingly;
(1) Starting from STBCKI="L"
STDATO will be output synchronizing with the rising edge of STBCKI.
(2) Starting from STBCKI="H".
STDATO will be output synchronizing with the falling edge of SBCKI.
Using each mode of (1) or (2) does not change the output characteristics.
