X = don’t care

SCKL_POL is used to select the working polarity of the Input Serial Clock (SCKR).

(1) If SCKL_POL is set to 0x00, the data (SDI) are sent with the falling edge of SCKR and sampled on the

rising edge.

(2) If SCKL_POL is set to 0x04, the data (SDI) are sent with the rising edge of SCKR and sampled on the

falling edge.
