Description
Reset Port. Each bit indicates if the corresponding port is held in reset (1). By asserting and
then de-asserting this bit for a port, the internal state associated with that port is reset so that
the port is in the Disabled state (see Section 5.2 on page 256). This register should not be left
asserted. Do not use this register to keep ports in the inactive state. Instead, use the SENBPRT
register to enable or disable ports.
