Notes
21. The 33977 shall meet all SPI interface timing requirements specified in the SPI Interface Timing section of this table, over the specified
temperature range. Digital interface timing is based on a symmetrical 50 percent duty cycle SCLK Clock Period of 33 ns. The device shall
be fully functional for slower clock speeds.
22. Time required for output status data to be terminated at SO 1.0 kΩ load on SO.
23. Time required for output status data to be available for use at SO 1.0 kΩ load on SO.
24. Time required to obtain valid data out from SO following the rise of SCLK.
