SPI INTERFACE TIMING
Notes :
1. RSTB low duration measured with outputs enabled and going to OFF or disabled condition.
2. Maximum setup time required for the QHSOLSS is the minimum guaranteed time needed from the micro.
3. Rise and Fall time of incoming SI, CSB, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
4. Time required for output status data to be available for use at SO. 1 K Ohm pullup on CSB
5. Time required for output status data to be terminated at SO. 1 K Ohm pullup on CSB
6. Time required to obtain valid data out from SO following the rise of SCLK.
