21.3.2.17 Endpoint Initialization Register (ENDPTPRIME)—Non-EHCI
This register is not defined in the EHCI specification. This register is used to initialize endpoints. It is only
used in device mode.

for a transmit operation in order to respond to a USB IN/INTERRUPT transaction. Software should write a one
to the corresponding bit when posting a new transfer descriptor to an endpoint. Hardware will automatically use
this bit to begin parsing for a new transfer descriptor from the queue head and prepare a transmit buffer.
Hardware will clear this bit when the associated endpoint(s) is (are) successfully primed. PETB[5] (bit 21 of the
register) corresponds to endpoint 5.

Setup endpoint status. For every setup transaction that is received, a corresponding bit in this
register is set. Software must clear or acknowledge the setup transfer by writing a one to a respective
bit after it has read the setup data from 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 is engaged.
This register is only used in device mode.
