Hello, I've got an issue when I use a low external frequency (32kHz) on C8051F350. In classic case, this frequency is used to have a very low consommation. I would like to switch to internal 3.0625MHz ONLY DURING SMBus transaction. But when I generate a transaction on SMBus, the interrupt is ignored. If I keep only internal frequency, there is any problem, the interrupt is correctly detected. Can you help me to understand the issue ? (Sorry for my english)
