Does anyone know what the behavior is when using a high-speed iso IN EP in auto-switch mode concerning the FIFOCON and TXINI bits in the given EP status register and how to address each bank of the EP buffer?

1.) Is it still necessary to clear TXINI AND FIFCON when using the auto-switch bank feature with iso endpoints?

2.) Are the banks for a given iso ep just contiguous in the Virtual Ep DPRAM allocated memory? i.e., EP1 2-banks of 256 bytes each... Would you address them as EP1VIRTUAL + 0 and EP1VIRTUAL+256 ?

I'm having a bit of a time figuring this out from the docs.
