This field contains the maximum value in millisecond of the polling period for an Interrupt Pipe.
This value has no effect for a non-Interrupt Pipe.
This field is cleared upon sending a USB reset.
This field contains the Ping/Bulk-out period.
If BINTERVAL>0 and PINGEN=1, one PING token is sent every BINTERVAL micro-frame until it is ACKed by the peripheral.
If BINTERVAL=0 and PINGEN=1, multiple consecutive PING token is sent in the same micro-frame until it is ACKed.
If BINTERVAL>0 and PINGEN=0, one OUT token is sent every BINTERVAL micro-frame until it is ACKed by the peripheral.
If BINTERVAL=0 and PINGEN=0, multiple consecutive OUT token is sent in the same micro-frame until it is ACKed.
This value must be in the range from 0 to 255.
This bit is relevant for High-speed Bulk-out transaction only (including the control data stage and the control status stage).
Writing a zero to this bit will disable the ping protocol.
Writing a one to this bit will enable the ping mechanism according to the usb 2.0 standard.
This bit is cleared upon sending a USB reset.
This field contains the number of the endpoint targeted by the pipe. This value is from 0 to 15.
This field is cleared upon sending a USB reset.
This field contains the pipe type.
