Description
Controller mode
The controller defaults to an idle state and needs to be initialized to the
desired operating mode after reset. This register can only be written once
after reset. If it is necessary to switch modes, software must reset the
controller by writing to the RESET bit in the USBCMD register before
reprogramming this register.

Endian select
This bit can change the byte ordering of the transfer buffers to match the
host microprocessor bus architecture. The bit fields in the microprocessor
interface and the DMA data structures (including the setup buffer within the
device QH) are unaffected by the value of this bit, because they are based
upon 32-bit words.
Little endian: first byte referenced in least significant byte of 32-bit word.
Big endian: first byte referenced in most significant byte of 32-bit word.
Setup Lockout mode
In device mode, this bit controls behavior of the setup lock mechanism. See
Section
Setup Lockouts on
Setup Lockouts Off (DCD requires the use of Setup Buffer Tripwire in
USBCMD)
