SPI Master Mode Timing Parameter Description Min Typ Max Unit tSL SCLK low pulse width1 (SPIDIV + 1) × tUCLK ns tSH SCLK high pulse width1 (SPIDIV + 1) × tUCLK ns tDAV Data output valid after SCLK edge 0 35.5 ns tDOSU Data output setup time before SCLK edge1 (SPIDIV + 1) × tUCLK ns tDSU Data input setup time before SCLK edge 58.7 ns tDHD Data input hold time after SCLK edge 16 ns tDF Data output fall time 12 35.5 ns tDR Data output rise time 12 35.5 ns tSR SCLK rise time 12 35.5 ns tSF SCLK fall time 12 35.5 ns 1 tUCLK = 62.5 ns. It corresponds to the internal 16 MHz clock before the clock divider.
