Port Power Control Mask: Bit 15 corresponds to Port 15, Bit 14 corresponds to Port 14, the remaining bits follow suit.
Unimplemented ports are reserved.
0 = Device not removable
1 = Global power mask
This field is only valid if No Power Switching bit (MEMOFST 49h[1]) is cleared and Power Switching Mode Bit (MEMOFST
49h[0]) is set (individual port switching). When set, the port only responds to individual port power switching commands
(Set/ClearPortPower, MEMOFST 54h[1:0] and 58h[1:0]). When cleared, the port only responds to global power switching
commands (Set/ClearGlobalPower, MEMOFST 52h[0] and 50h[0]).
