Bit Descriptions
FSE4-FSE1: Port power priority bits to support Fast Shutdown; one bit per port. It is used to specify which port or ports is/are shut down in response to an external assertion of the SHTDWN pin fast shutdown signal. The turn-off procedure is similar to a port reset using Reset command (Reset register). If one of these bits is set while the SHTDWN pin is low, that port is shut down as well.
1 = When the SHTDWN is forced to a low level, the corresponding port is powered off.
0 = SHTDWN signal has no impact on the port.
Reserved: Bits R15[3:0] are reserved for future use. Undesirable behavior may result if the value of these bits are changed from their reset value.
