MFS channel 0,1 and 3 are without FIFO. Instead, please use channel 4,6 or 7 which has FIFO.
Thanks Geon. This leads me to the next question: how does one select the MFS channel? I don’t see this as a selection in the component configuration? Is there an API call, or do you have to add a bunch of unused MFS component to the top design to get up to channel 4?
