In several examples, I see the reset pin of the SPI Master left unconnected.
is it OK to leave a SPIM block's reset pin open?
The Default value of reset pin is set to 1'b0 and it is not necessary to connect anything as well.
So even if you leave Reset pin floating, it will be shorted to Vssd by default.
Nobody asked this question. Please what are you going to tell us here?
