Descriptions
Bit Field Value Description
31–0 TX_CP 00000000h This field is the memory address for the transmit queue completion pointer. This
to register is written by the DSP core with the buffer descriptor address for the last
FFFFFFFFh buffer processed by the host during interrupt processing. The port uses the value
written to determine if the interrupt should be deasserted.
