Rx Completion Pointer Register - This register is written by the host
with the buffer descriptor address for the last buffer processed by the
host during interrupt processing.
The port uses the value written to determine if the interrupt should
be deasserted.
Note: The value read is the completion pointer (interrupt
acknowledge) value that was written by the CPDMA DMA controller
(port).
The value written to this register by the host is compared with the
value that the port wrote to determine if the interrupt should remain
asserted.
The value written is not actually stored in the location.
The interrupt is deasserted if the two values are equal.
14.5.6 CPSW_PORT Registers
lists the memory-mapped registers for the CPSW_PORT. All register offset addresses not
listed in
should be considered as reserved locations and the register contents should not be
modified.
