STV0672-chipsetf-3-1.fm
by the state of the Digiport bus bits. The Digiport also controls the device current consumption that is reported to the host at
device enumeration. The current reference design for the STV0672-chipset has Digiport[7:0] connected to VSS, thus the VID and
PID are 16’h0553 and 16’h0100 respectively.
