The status inputs are debounced using a 1 msec time constant. Values on the status
inputs that do not persist for more than 1 msec will not cause an update of the status input
register or cause an OTG interrupt.
Description
VBUS_Discharge
Setting this bit to 1 causes VBUS to discharge through a resistor.
VBUS_Charge
Setting this bit to 1 causes the VBUS line to be charged. This is used for
VBUS pulsing during SRP.
Hardware assist auto_reset
Disabled
Enable automatic reset after connect on host port.
OTG termination
This bit must be set to 1 when the OTG controller is in device mode. This
controls the pull-down on USB_DM.
Data pulsing
Setting this bit to 1 causes the pull-up on USB_DP to be asserted for data
pulsing during SRP.
ID pull-up.
This bit provides control over the pull-up resistor.
Pull-up off. The ID bit will not be sampled.
Pull-up on.
Hardware assist data pulse
Write a 1 to start data pulse sequence.
Hardware assist B-disconnect to A-connect
Disabled.
Enable automatic B-disconnect to A-connect sequence.
USB ID
A-device
B-device
A-VBUS valid
Reading 1 indicates that VBUS is above the A-VBUS valid threshold.
A-session valid
Reading 1 indicates that VBUS is above the A-session valid threshold.
B-session valid
Reading 1 indicates that VBUS is above the B-session valid threshold.
B-session end
Reading 1 indicates that VBUS is below the B-session end threshold.
1 millisecond timer toggle
This bit toggles once per millisecond.
Data bus pulsing status
Reading a 1 indicates that data bus pulsing is detected on the port.
