(1) Clock Mode 0 (clk polarity = 0 ; clk phase = 0 ) is the mode of operation.
(2) The Device captures data on the falling clock edge in Clock Mode 0, as opposed to the traditional rising clock edge. Although non-standard, the falling-edge-based setup and hold time timings have been designed to be compatible with standard SPI sevices that launch data on the falling edge in Clock Mode 0.
(3) P = SCLK period in ns.
