Bits 14:11 Reserved
Bits 10:0 MPSIZ: Maximum packet size
Bit 17 NAKSTS: NAK status
Bit 16 EONUM: Even/odd frame
Bit 15 USBAEP: USB active endpoint
Indicates the following:
When either the application or the core sets this bit:
Irrespective of this bit’s setting, the core always responds to SETUP data packets with an
ACK handshake.
Applies to isochronous IN and OUT endpoints only.
Indicates the frame number in which the core transmits/receives isochronous data for this
endpoint. The application must program the even/odd frame number in which it intends to
transmit/receive isochronous data for this endpoint using the SEVNFRM and SODDFRM
fields in this register.
DPID: Endpoint data PID
Applies to interrupt/bulk OUT endpoints only.
Contains the PID of the packet to be received or transmitted on this endpoint. The application
must program the PID of the first packet to be received or transmitted on this endpoint, after
the endpoint is activated. The application uses the SD0PID register field to program either
DATA0 or DATA1 PID.
Indicates whether this endpoint is active in the current configuration and interface. The core
clears this bit for all endpoints (other than EP 0) after detecting a USB reset. After receiving
the SetConfiguration and SetInterface commands, the application must program endpoint
registers accordingly and set this bit.
The application must program this field with the maximum packet size for the current logical
endpoint. This value is in bytes.
0: The core is transmitting non-NAK handshakes based on the FIFO status.
1: The core is transmitting NAK handshakes on this endpoint.
The core stops receiving any data on an OUT endpoint, even if there is space in the
RxFIFO to accommodate the incoming packet.
0: Even frame
1: Odd frame
0: DATA0
1: DATA1
