USB on-the-go full-speed (OTG_FS) RM0008 Figure 262. USB peripheral-only connection V DD (2) 5V to V DD Volatge regulator (1) STM32F105xx STM32F107xx OSC_IN OSC_OUT PA9 PA11 PA12 VBUS DM DP V SS USB Std-B connector ai17116 1. Use a regulator to build a bus-powered device. 2. V DD range between 2 V and 3.6 V. 26.5.1 SRP-capable peripheral The SRP capable bit in the Global USB configuration register (SRPCAP bit in OTG_FS_GUSBCFG) enables the OTG_FS to support the session request protocol (SRP). In this way, it allows the remote A-Device to save power by switching off V BUS while the USB session is suspended. The SRP peripheral mode program model is described in detail in the B-device session request protocol section. 26.5.2 Peripheral states Powered state The V BUS input detects the B-Session valid voltage by which the USB peripheral is allowed to enter the powered state (see USB2.0 par9.1). The OTG_FS then automatically connects the DP pull-up resistor to signal full-speed device connection to the host and generates the session request interrupt (SRQINT bit in OTG_FS_GINTSTS) to notify the powered state. The V BUS input also ensures that valid V BUS levels are supplied by the host during USB operations. If a drop in V BUS below B-session valid happens to be detected (for instance because of a power disturbance or if the host port has been switched off), the OTG_FS automatically disconnects and the session end detected (SEDET bit in OTG_FS_GOTGINT) interrupt is generated to notify that the OTG_FS has exited the powered state. In the powered state, the OTG_FS expects to receive some reset signaling from the host. No other USB operation is possible. When a reset signaling is received the reset detected interrupt (USBRST in OTG_FS_GINTSTS) is generated. When the reset signaling is complete, the enumeration done interrupt (ENUMDNE bit in OTG_FS_GINTSTS) is generated and the OTG_FS enters the Default state. 700/995 Doc ID 13902 Rev 9
RM0008 USB on-the-go full-speed (OTG_FS) Soft disconnect The powered state can be exited by software with the soft disconnect feature. The DP pullup resistor is removed by setting the soft disconnect bit in the device control register (SDIS bit in OTG_FS_DCTL), causing a device disconnect detection interrupt on the host side even though the USB cable was not really removed from the host port. Default state In the Default state the OTG_FS expects to recieve a SET_ADDRESS command from the host. No other USB operation is possible. When a valid SET_ADDRESS command is decoded on the USB, the application writes the corresponding number into the device address field in the device configuration register (DAD bit in OTG_FS_DCFG). The OTG_FS then enters the address state and is ready to answer host transactions at the configured USB address. Suspended state The OTG_FS peripheral constantly monitors the USB activity. After counting 3 ms of USB idleness, the early suspend interrupt (ESUSP bit in OTG_FS_GINTSTS) is issued, and confirmed 3 ms later, if appropriate, by the suspend interrupt (USBSUSP bit in OTG_FS_GINTSTS). The device suspend bit is then automatically set in the device status register (SUSPSTS bit in OTG_FS_DSTS) and the OTG_FS enters the suspended state. The suspended state may optionally be exited by the device itself. In this case the application sets the remote wakeup signaling bit in the device control register (WKUPINT bit in OTG_FS_DCTL) and clears it after 1 to 15 ms. When a resume signaling is detected from the host, the resume interrupt (RWUSIG bit in OTG_FS_GINTSTS) is generated and the device suspend bit is automatically cleared. 26.5.3 Peripheral endpoints The OTG_FS core instantiates the following USB endpoints: ● Control endpoint 0 – is bidirectional and handles control messages only – has a separate set of registers to handle in and out transactions – has proper control (DIEPCTL0/DOEPCTL0), transfer configuration (DIEPTSIZ0/DIEPTSIZ0), and status-interrupt (DIEPINTx/)DOEPINT0) registers. The available set of bits inside the control and transfer size registers slightly differs from that of other endpoints ● 3 IN endpoints – each of them can be configured to support the isochronous, bulk or interrupt transfer type – each of them has proper control (DIEPCTLx), transfer configuration (DIEPTSIZx), and status-interrupt (DIEPINTx) registers – the Device IN endpoints common interrupt mask register (DIEPMSK) is available to enable/disable a single kind of endpoint interrupt source on all of the IN endpoints (EP0 included) – support incomplete isochronous IN transfer interrupt (IISOIXFR bit in OTG_FS_GINTSTS), asserted when there is at least one isochronous IN endpoint Doc ID 13902 Rev 9 701/995
