Description
Setup time between data and the rising edge of SCLK
Hold time between data and the rising edge of SCLK
Period of the clock
Setup time between the CS falling edge and SCLK rising edge (start of the communication cycle)
Setup time between the SCLK rising edge and CS rising edge (end of the communication cycle)
Minimum period that SCLK should be in a logic high state
Minimum period that SCLK should be in a logic low state
