Notes

38.

Parameters guaranteed by design.

39.

RSTB low duration measured with outputs enabled and going to OFF or disabled condition.

40.

Maximum setup time required for the 10XSC425 is the minimum guaranteed time needed from the microcontroller.

41.

Rise and Fall time of incoming SI, CSB, and SCLK signals suggested for design consideration to prevent the occurrence of double

pulsing.

42.

Time required for output status data to be available for use at SO. 1.0 k

on pull-up on CSB.

43.

Time required for output status data to be terminated at SO. 1.0 k

on pull-up on CSB.
