Name Description Access
mode Returns the current mode: 0 for device mode, 1 for host mode Read
hnpcapable Gets or sets the "HNP-capable" bit in the Core USB Configuraton Register. + Read returns the current value. Read/Write
srpcapable Gets or sets the "SRP-capable" bit in the Core USB Configuraton Register. + Read returns the current value. Read/Write
hnp Initiates the Host Negotiation Protocol. Read returns the status. Read/Write
srp Initiates the Session Request Protocol. Read returns the status. Read/Write
buspower Gets or sets the Power State of the bus (0 - Off or 1 - On) Read/Write
bussuspend Suspends the USB bus. Read/Write
busconnected Gets the connection status of the bus Read
gotgctl Gets or sets the Core Control Status Register. Read/Write
gusbcfg Gets or sets the Core USB Configuration Register Read/Write
grxfsiz Gets or sets the Receive FIFO Size Register Read/Write
gnptxfsiz Gets or sets the non-periodic Transmit Size Register Read/Write
gpvndctl Gets or sets the PHY Vendor Control Register Read/Write
ggpio Gets the value in the lower 16-bits of the General Purpose IO Register + or sets the upper 16 bits. Read/Write
guid Gets or sets the value of the User ID Register Read/Write
gsnpsid Gets the value of the Synopsys ID Regester Read
devspeed Gets or sets the device speed setting in the DCFG register Read/Write

phy_typeSpecifies the type of PHY interface to use. By default, the driver will + automatically detect the phy_type. + - 0: Full Speed + - 1: UTMI+ (default, if available) + - 2: ULPI +
phy_utmi_widthSpecifies the UTMI+ Data Width. This parameter is applicable for a + phy_type of UTMI+. Also, this parameter is applicable only if the + OTG_HSPHY_WIDTH cC parameter was set to "8 and 16 bits", meaning that the + core has been configured to work at either data path width. + - Values: 8 or 16 bits (default 16) +
phy_ulpi_ddrSpecifies whether the ULPI operates at double or single data rate. This + parameter is only applicable if phy_type is ULPI. + - 0: single data rate ULPI interface with 8 bit wide data bus (default) + - 1: double data rate ULPI interface with 4 bit wide data bus +
i2c_enableSpecifies whether to use the I2C interface for full speed PHY. This + parameter is only applicable if PHY_TYPE is FS. + - 0: Disabled (default) + - 1: Enabled +
otg_en_multiple_tx_fifoSpecifies whether dedicatedto tx fifos are enabled for non periodic IN EPs. + The driver will automatically detect the value for this parameter if none is + specified. + - 0: Disabled + - 1: Enabled (default, if available) +
dev_tx_fifo_size_n (n = 1 to 15)Number of 4-byte words in each of the Tx FIFOs in device mode + when dynamic FIFO sizing is enabled. + - Values: 4 to 768 (default 256) +
