DS90UB925Q-Q1: toggling PDB during external PCLK is supplied

K.Yaita

Hi Team,

I believe toggling PDB (High -> Low or Low -> High) is effective regardless of during external PCLK is supplied.
I assume power supply of DS90UB925Q-Q1 is already supplied in this case.

Is my understanding correct?

Yes, this is correct. When performing a PDB reset, after bringing PDB high to low please wait for for 2ms before bringing back high again.
