Device State Control Register 0
| RHST | USB Bus Reset Status 0 (others): USB bus reset in progress(When the host controller function is selected) 0 (000): Communication speed not determined 1 (001): Low-speed connection(When the host controller is selected) /USB bus reset in progress( When the function controller is selected) 2 (010): Full-speed connection(When the host controller is selected) /USB bus reset in progress or full-speed connection(When the function controller is selected) 3 (011): Setting prohibited |
| UACT | USB Bus Enable 0 (0): Downstream port is disabled (SOF transmission is disabled). 1 (1): Downstream port is enabled (SOF transmission is enabled). |
| RESUME | Resume Output 0 (0): Resume signal is not output. 1 (1): Resume signal is output. |
| USBRST | USB Bus Reset Output 0 (0): USB bus reset signal is not output. 1 (1): USB bus reset signal is output. |
| RWUPE | Wakeup Detection Enable 0 (0): Downstream port wakeup is disabled. 1 (1): Downstream port wakeup is enabled. |
| WKUP | Wakeup Output 0 (0): Remote wakeup signal is not output. 1 (1): Remote wakeup signal is output. |
| VBUSEN | USB0_VBUSEN Output Pin Control 0 (0): External USB0_VBUSEN pin outputs low 1 (1): External USB0_VBUSEN pin outputs high |
| EXICEN | USB0_EXICEN Output Pin Control 0 (0): External USB0_EXICEN pin outputs low 1 (1): External USB0_EXICEN pin outputs high |
| HNPBTOA | Host Negotiation Protocol (HNP) Control This bit is used when switching from device B to device A while in OTG mode. If the HNPBTOA bit is 1, the internal function control keeps the suspended state until the HNP processing ends even though SYSCFG.DPRPU = 0 or SYSCFG.DCFM = 1 is set. 0 (0): Normal Operation 1 (1): Switching from device B to device A is enabled |
