TM4C1294NCPDT: Ethernet Errata exact workaround for TM4C1294NCPDT

Part Number: TM4C1294NCPDT

We have a query related to ERRATA of TM4C1294NCPDT as follows

 

In Errata document the workaround is given as below. It says to write 1 to FLASHCONF.FPFOFF before initialization of Ethernet MAC and PHY. Then clearing the same bit after Initialization.


As per datasheet, bit 16 and 17 of FLASHCONF register are FPFOFF and  FPFON.

However as per datasheet to make Force Prefetch OFF, user has to set FPFOFF bit and to make Force Prefetch ON user has to set FPFON bit.

As seen there is no effect when bit is cleared as per data sheet.

Let us know the exact code required in the workaround.
