TMS570LS3137: MIBSPI#139 - Mibspi RX RAM RXEMPTY bit does not get cleared after reading.

Part Number: TMS570LS3137

we are developing an application using TMS570ls3137, as part of it we are examining all the errata points. In the errata it has been mentioned that "The MibSPI RXEMPTY flag is auto-cleared after a CPU or DMA read." This is not clear. Per TRM the flag "RXEMPTY" is set after the data read from "SPIBUF" register. Hence the errata description is bit ambiguous. Can you explain the errata description and it's work around in detail.
