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

remote_wakeup On read, shows the status of Remote Wakeup. On write, initiates a remote ++ wakeup of the host. When bit 0 is 1 and Remote Wakeup is enabled, the Remote ++ Wakeup signalling bit in the Device Control Register is set for 1 ++ milli-second. Read/Write
regdump Dumps the contents of core registers. Read
spramdump Dumps the contents of core registers. Read
hcddump Dumps the current HCD state. Read
hcd_frrem Shows the average value of the Frame Remaining ++ field in the Host Frame Number/Frame Remaining register when an SOF interrupt ++ occurs. This can be used to determine the average interrupt latency. Also ++ shows the average Frame Remaining value for start_transfer and the "a" and ++ "b" sample points. The "a" and "b" sample points may be used during debugging ++ bto determine how long it takes to execute a section of the HCD code. Read
rd_reg_test Displays the time required to read the GNPTXFSIZ register many times ++ (the output shows the number of times the register is read). ++ Read
wr_reg_test Displays the time required to write the GNPTXFSIZ register many times ++ (the output shows the number of times the register is written). ++ Read
