Notes
19.

21.
22.
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.
Guaranteed by design.
For information only.
Delay starts at falling edge of clock cycle #8 of the SPI command and start of device activation/deactivation.
