          I am having a problem where the 9S12NE CPU resets when EPHYEN bit is set. I have allocated RAM space for the Rx buffers and Txbuffer.
RAM starts at $2000.
RxbufferA is at $2000, RxbufferB is at $2200 and Txbuffer is at $2300.( all buffers are 256 long )
I have a little more than 5K of RAM left for the application.
The EMACE bit is disabled.
Any hints to the problem will be much appreciated.
