Notes
24.
This parameter is guaranteed by process monitoring but is not production tested.
25.
Delay between turn-on or turn-off command and high side on or high side off, excluding rise or fall time due to external load.
26.
Delay between the end of the SPI command (rising edge of the SS) and start of device activation/deactivation.
27.
This parameter is guaranteed by process monitoring but it is not production tested.
