pub type R_PORT_POWER_STATUS_W_SET_PORT_POWER_R = BitReader<bool>;

Field r_port_power_status_w_set_port_power reader - (read) PortPowerStatus

This bit reflects the port’s power status, regardless of the type of power switching implemented. This bit is cleared if an overcurrent condition is detected. HCD sets this bit by writing SetPortPower or SetGlobalPower. HCD clears this bit by writing ClearPortPower or ClearGlobalPower. Which power control switches are enabled is determined by PowerSwitchingMode and PortPortControlMask[NumberDownstreamPort]. In global switching mode(PowerSwitchingMode=0), Set/ClearGlobalPower controls this bit. In per-port power switching (PowerSwitchingMode=1), if the PortPowerControlMask[NDP] bit for the port is set, only Set/ClearPortPower commands are enabled. If the mask is not set, only Set/ClearGlobalPower commands are enabled. When port power is disabled, CurrentConnectStatus, PortEnableStatus, PortSuspendStatus, and PortResetStatus should be reset.

0 port power is off

1 port power is on

(write) SetPortPower

The HCD writes a ‘1’ to set the PortPowerStatus bit. Writing a ‘0’ has no effect.

Note: This bit is always reads ‘1b’ if power switching is not supported.
