From MCF5253 Reference manual https://www.nxp.com/docs/en/reference-manual/MCF5253RM.pdf

Host mode: Port Change Detect. The controller sets this bit to a one when on any port a Connect Status occurs, a PortEnable/Disable Change occurs, an Over Current Change occurs, or the Force Port Resume bit is set as theresult of a J-K transition on the suspended port.
