10.16.15 PROT_EPO_CS1 (continued)
22 STREAMNRDY_MASK Interrupt mask for STREAMNRDY bit
21 FLOWCONTROL_MASK Interrupt mask for FLOWCONTROL bit
20 RETRY_MASK Interrupt mask for RETRY bit
19 COMMIT_MASK Interrupt mask for COMMIT bit
18 FIRST_ACK_NUMP_0 The NumP for the first ACK is zero.
17 STREAM_ERROR Stream Error occurred.
16 DBTERM The Burst was terminated by the device when the MULT_TIMER expires.
15 HBTERM The Burst Was terminated by the host.
14 OOSERR Out Of Sequence Error. Anytime an OUT-DATA is received with unexpected sequence
number request, the data will be dropped and intr will be raised
13 SHORT Indicates a shorter-than-maxsize packet was received.
12 ZERO Indicates a zero length packet was received by the device in an OUT transaction. Must be
cleared by software.
11 STREAMNRDY Nrdy was sent for a bulk stream request because of EP-stream not present in the mapper.
10 FLOWCONTROL EP in flow control due to EPM not being available.
9RETRY Whenever the USB3.0 does a retry it will asserts this interrupt.
8 COMMIT Set whenever an OUT DATA was committed into the EPM.
5 STREAM_ERROR_STALL_EN Issue STALL whenever Stream error occurs.
4 EP_RESET Per End Point Reset.
3STREAM_EN Enables bulk stream protocol handling for this EP
2STALL Set this bit to “1” to stall an endpoint, and to “0” to clear a stall.
1 NRDY Setting this bit causes NRDY on IN transactions.
0VALID Set VALID=1 to activate an endpoint, and VALID=0 to de-activate it. All USB endpoints
default to invalid. An endpoint whose VALID bit is 0 does not respond to any USB traffic.
