21.3.3.17 Endpoint Setup Status Register (EPSETUPSR)
This register is not defined in the EHCI specification. This register contains the endpoint setup status and
is used only by the USB OTG module in device mode.
21.3.3.18 Endpoint Initialization Register (EPPRIME)
This register is not defined in the EHCI specification. This register is used to initialize endpoints and is
used only by the USB OTG module in device mode.

ES
Endian select. Controls the byte ordering of the transfer buffers to match the host microprocessor bus architecture.
The bit fields in the register 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.
0 Little endian. First byte referenced in least significant byte of 32-bit word.
1 Big endian. First byte referenced in most significant byte of 32-bit word.
Note: For proper operation, this bit must be set for this ColdFire device.
1–0
CM
Controller mode. This register can be written only once after reset. If necessary to switch modes, software must
reset the controller by writing to the USBCMD[RST] bit before reprogramming this register.
00 Idle (default for the USB OTG module)
01 Reserved
10 Device controller
11 Host controller (default for the USB host module)
Note: The USB OTG module must be initialized to the desired operating mode after reset.

EPSETUPSTAT
Setup endpoint status. For every setup transaction received, a corresponding bit in this field is set.
Software must clear or acknowledge the setup transfer by writing a 1 to a respective bit after it has read
the setup data from the queue head. The response to a setup packet, as in the order of operations and
total response time, is crucial to limit bus time outs while the setup lockout mechanism engages.
