impl W

source

pub fn r_local_power_status_w_clear_global_power( &mut self, ) -> R_LOCAL_POWER_STATUS_W_CLEAR_GLOBAL_POWER_W<'_, 0>

Bit 0 - (Read)LocalPowerStatus

When read, this bit returns the LocalPowerStatus of the Root Hub. The Root Hub does not support the local power status feature; thus, this bit is always read as ‘0’.

(Write)ClearGlobalPower

When write, this bit is operated as the ClearGlobalPower. In global power mode ( PowerSwitchingMode =0), This bit is written to ‘1’ to turn off power to all ports (clear PortPowerStatus ). In per-port power mode, it clears PortPowerStatus only on ports whose PortPowerControlMask bit is not set. Writing a ‘0’ has no effect.

source

pub fn over_current_indicator(&mut self) -> OVER_CURRENT_INDICATOR_W<'_, 1>

Bit 1 - This bit reports overcurrent conditions when the global reporting is implemented. When set, an overcurrent condition exists. When cleared, all power operations are normal. If per-port overcurrent protection is implemented this bit is always ‘0’

source

pub fn r_device_remote_wakeup_enable_w_set_remote_wakeup_enable( &mut self, ) -> R_DEVICE_REMOTE_WAKEUP_ENABLE_W_SET_REMOTE_WAKEUP_ENABLE_W<'_, 15>

Bit 15 - (read)DeviceRemoteWakeupEnable

This bit enables a ConnectStatusChange bit as a resume event, causing a USBSUSPEND to USBRESUME state transition and setting the ResumeDetected interrupt.

0 ConnectStatusChange is not a remote wakeup event.

1 ConnectStatusChange is a remote wakeup event.

(write)SetRemoteWakeupEnable

Writing a ‘1’ sets DeviceRemoveWakeupEnable. Writing a ‘0’ has no effect.

source

pub fn r_local_power_status_w_set_global_power( &mut self, ) -> R_LOCAL_POWER_STATUS_W_SET_GLOBAL_POWER_W<'_, 16>

Bit 16 - (read)LocalPowerStatusChange

The Root Hub does not support the local power status features, thus, this bit is always read as ‘0’.

(write)SetGlobalPower

In global power mode ( PowerSwitchingMode =0), This bit is written to ‘1’ to turn on power to all ports (clear PortPowerStatus ). In per-port power mode, it sets PortPowerStatus only on ports whose PortPowerControlMask bit is not set. Writing a ‘0’ has no effect.

source

pub fn over_current_indicator_change( &mut self, ) -> OVER_CURRENT_INDICATOR_CHANGE_W<'_, 17>

Bit 17 - This bit is set by hardware when a change has occurred to the OverCurrentIndicator field of this register. The HCD clears this bit by writing a ‘1’. Writing a ‘0’ has no effect.
