How to check if the slew rate level is correctly set?

Slew rate can be read back in SR programming mode via IS pin.

The SR level can be read back in slew rate programming mode . The two paramters IIS(SR0) and IIS(SR_step) are necessary for this.
Attached is an example from out of the app note "Typical application waveforms".
