Descriptions
Bit Field Value Description
31-0 RX_HDP Rx Queue Head Descriptor Pointer: This field is the host memory address for the first buffer
descriptor in the channel receive queue. This field is written by the host to initiate queue receive
operations and is zeroed by the port when all free buffers have been used. An error condition
results if the host writes this field when the current field value is nonzero. The address must be
32-bit word aligned.
