Register Descriptions
The LM3S5791 USB controller has On-The-Go (OTG) capabilities as specified in the USB0 bit field
in the DC6 register (see page 257).
This icon indicates that the register is used in OTG B or Device mode. Some registers are used for
both Host and Device mode and may have different bit definitions depending on the mode.
This icon indicates that the register is used in OTG A or Host mode. Some registers are used for
both Host and Device mode and may have different bit definitions depending on the mode. The
USB controller is in OTG B or Device mode upon reset, so the reset values shown for these registers
apply to the Device mode definition.
This icon indicates that the register is used for OTG-specific functions such as ID detection and
negotiation. Once OTG negotiation is complete, then the USB controller registers are used according
to their Host or Device mode meanings depending on whether the OTG negotiations made the USB
controller OTG A (Host) or OTG B (Device).
