Access:
• INTFRQ: Pipe Interrupt Request Frequency
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.
• BINTERVAL: bInterval parameter for the Bulk-Out/Ping transaction
This field contains the Ping/Bulk-out period.
This value must be in the range from 0 to 255.
• PINGEN: Ping Enable
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.
• PEPNUM: Pipe Endpoint Number
This field contains the number of the endpoint targeted by the pipe. This value is from 0 to 10.
This field is cleared upon sending a USB reset.
