Limits based on characterization results, not production tested.
The CS , SCLK, SDI, and SDO pins are not internally pulled up or down; they must be driven for proper operation.
Limits are based on characterization results, characterized with f
The timing values are measured corresponding to the input thresholds (V

Description
CS falling edge to SCLK falling edge
SCLK rising edge to CS rising edge
CS rising edge to SDO disabled
CS deassertion between SPI communications
SPI clock frequency
1/(SPI clock frequency) mark-space ratio for the SCLK input is 40/60 to 60/40
SCLK low pulse width (space)
SCLK high pulse width (mark)
SCLK falling edge to SDO transition
SDI valid before SCLK rising edge
SDI valid after SCLK rising edge
