Definition
The minimum duration of time chip select, CS, must be
LOW before the first SCLK rising edge.
The minimum SCLK period.
Duty cycle tolerated by SCLK.
Minimum input setup time.
The minimum duration of time between the last SCLK
command word (or data word if the Auto-Increment bit is
HIGH) and the first SCLK of the data word (write cycle).
The minimum duration of time between the last SCLK
command word (or data word if the Auto-Increment bit is
HIGH) and the first SCLK of the data word (read cycle).
Minimum output hold time (15pF load).
The minimum duration of time between the last SCLK of
the GSPI transaction and when CS can be set HIGH.
Minimum input hold time.
