USB PHY VBUS Detect Control Register
VBUSVALID_THRESH | Sets the threshold for the VBUSVALID comparator 0 (000): 4.0 V 1 (001): 4.1 V 2 (010): 4.2 V 3 (011): 4.3 V 4 (100): 4.4 V (Default) 5 (101): 4.5 V 6 (110): 4.6 V 7 (111): 4.7 V |
VBUS_OVERRIDE_EN | VBUS detect signal override enable 0 (0): Use the results of the internal VBUS_VALID and Session Valid comparators for VBUS_VALID, AVALID, BVALID, and SESSEND (Default) 1 (1): Use the override values for VBUS_VALID, AVALID, BVALID, and SESSEND |
SESSEND_OVERRIDE | Override value for SESSEND |
BVALID_OVERRIDE | Override value for B-Device Session Valid |
AVALID_OVERRIDE | Override value for A-Device Session Valid |
VBUSVALID_OVERRIDE | Override value for VBUS_VALID signal sent to USB controller |
VBUSVALID_SEL | Selects the source of the VBUS_VALID signal reported to the USB controller 0 (0): Use the VBUS_VALID comparator results for signal reported to the USB controller (Default) 1 (1): Use the VBUS_VALID_3V detector results for signal reported to the USB controller |
VBUS_SOURCE_SEL | Selects the source of the VBUS_VALID signal reported to the USB controller 0 (00): Use the VBUS_VALID comparator results for signal reported to the USB controller (Default) 1 (01): Use the Session Valid comparator results for signal reported to the USB controller 2 (10): Use the Session Valid comparator results for signal reported to the USB controller 3 (11): Reserved, do not use |
VBUSVALID_TO_SESSVALID | Selects the comparator used for VBUS_VALID 0 (0): Use the VBUS_VALID comparator for VBUS_VALID results 1 (1): Use the Session End comparator for VBUS_VALID results. The Session End threshold is >0.8V and <4.0V. |
PWRUP_CMPS | Enables the VBUS_VALID comparator 0 (0): Powers down the VBUS_VALID comparator 1 (1): Enables the VBUS_VALID comparator (default) |
DISCHARGE_VBUS | Controls VBUS discharge resistor 0 (0): VBUS discharge resistor is disabled (Default) 1 (1): VBUS discharge resistor is enabled |
EN_CHARGER_RESISTOR | Enables resistors used for an older method of resistive battery charger detection 0 (0): Disable resistive charger detection resistors on USB_DP and USB_DP 1 (1): Enable resistive charger detection resistors on USB_DP and USB_DP |
