We are running it at 100 MHz, using the PLL. At least, I guess that qualifies as running it at 100 MHz.
So, asynch comms has never yet been done at 2 Mbps. Since initially posting this, I've found out that some other parts in the system are limited to 115K, so I believe we are going to have to reduce it, plus I would start to get a little worried about being able to service the comms at that rate along with everything else that the processor has to do. Although I guess if it has been done at 1 Mbps at a 25 MHz processor speed, then I guess we might be able to do 2 Mbps, simply based on processor speed.
I looked through the data sheet for the C8051F120 and didn't see anything mentioned about a speed limit on the UARTs, but I'll take another look.
Thanks!
