BOOSTXL-DRV8305EVM: i can't change the dead time

Part Number:BOOSTXL-DRV8305EVM

Dear all

I am using a BOOSTXL-DRV8305EVM with LAUNCHXL-F28069M.

I want to configure the DRV8305 via SPI to get a dead time of 1.76us, 

the SPI command that I sent is the following:

the orange signal represents the clock while the blue one represents the SDI signal.

and I got the following result when i read the 0x7 register:

as you can see, the value of the 0x7 register is 0000 0010 0101 0110 and the dead time bits are 101 which means that the dead time's value is 1.76us

but i can't see this dead time between the MOSFETs' outputs signals of the same leg.

can you please help me to resolve this problem?

thanks in advance;

best regards
