Controller mode
This register can only be written once after reset. If it is necessary to switch modes, software must reset the
controller by writing to USBCMD[RST] before reprogramming this register.

• Setting this bit ensures that overruns/underruns of the latency FIFO are eliminated for low bandwidth systems
• Note that time duration to pre-fill the FIFO becomes significant when stream disable is active. See
• Also note that in systems with high system bus utilization, setting this bit will ensure no overruns or underruns
• Setting this bit disables double priming on both RX and TX for low bandwidth systems. This mode ensures
• Note that in high-speed mode, all packets received will be responded to with a NYET handshake when stream

effect of ensuring the TX latency is filled to capacity before the packet is launched onto the USB.
