I am doing DMA transfers over an EPPI bus on a BF547 using VDK drivers.
The manual at:
says there is a 64KB limit for the value of ElementCount (DMAx_X_COUNT). I have looked this up in the hardware reference manual and I see a 16 bit register with no mention of what values can be put in here. So I need to know if this limitation is really one of bytes or of the element count, such that if the value of this register were maxed out at at 64k, and if the ElementWidth (DMAx_X_MODIFY) had a value of 2, could there be a total of 128kB transferred?
