Notes

15.
Maximum specified time for the 33970 is the minimum guaranteed time needed from the microcontroller.
The minimum and maximum value will vary proportionally to the internal clock tolerance. These numbers are based on an ideally
calibrated clock frequency of 1.0 MHz. These are not 100 percent tested.
The device shall meet all SPI interface timing requirements specified in
the SPI Interface Timing section of this table, over the temperature
range specified. Digital interface timing is based on a symmetrical 50 percent duty cycle SCLK Clock Period of 333 ns. The device shall
be fully functional for slower clock speeds. See
Figure 4
and
5
.
The maximum setup time specified for the 33970 is the minimum time needed from the microcontroller to guarantee correct operation.
Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
The value is for a 1.0 MHz calibrated internal clock. The value will change proportionally as the internal clock frequency changes
