Description
Port mask for combo port mode selection.
If the respective port bits in LED_FIB_PMASK_CTRL and LED_COPR_PMASK_CTRL are both set, the port LED peripheral will scan out signals for two port LEDs. It is also possible that a combo port only has been assigned one status (set of) LED(s). In this case, the port bit must be set in this register, to let the single LED follow both RJ45 and SFP link status.
If a port can only connect on one type of physical layer, i.e. only one of the PMASK_CTRL registers has a bit set, then this control bit most likely has no effect.
