Notes
36. Parameters guaranteed by design.
37. RSTB low duration measured with outputs enabled and going to OFF or disabled condition.
38. Maximum setup time required for the 07XSC200 is the minimum guaranteed time needed from the microcontroller.
39. Rise and Fall time of incoming SI, CSB, and SCLK signals suggested for design consideration to prevent the occurrence of double
pulsing.
40. Time required for output status data to be available for use at SO. 1.0 kon pull-up on CSB.
41. Time required for output status data to be terminated at SO. 1.0 kon pull-up on CSB.
