DRV8245S-Q1LEVM: It looks like that this motor driver doesn't act SSC(Spread Spectrum Clocking) feacture

Part Number: DRV8245S-Q1LEVM

[Test condition]

* PH/EN mode

* 20kHz/50% duty

Hi, I have DRV8245S-Q1LEVM(SPI, 'S' variant), and try to use SSC(Spread Spectrum Clocking) feature because of EMC.

On datasheet of DRV8245, i can enable/disable SSC function by writing SSC_DSI bit(CONFIG1 Register) --> refer to under screenshot pic.

However, it looks like dosen't any difference on Vout1, Vout2 waveform.

I want to make output waveform looks like under waveform(red arrow: setting frequency +-% frequency)

But it doesn't have no difference compared to each other(SSC_DSI = 1, SSC DSI = 0)

Please solve this problem.

Thank you.
