Hi,

I am working with a project on a 16f676. It is running on its internal 4MHz RC oscillator. It is using extensive interrutps. (Tmr0, Tmr1, INTF, Comparator). All of the interrupt routines are in ASM. Almost all pins are used. For debugging prupose I need to view a few registers. Only option is to use debug on one of the LED indicator.

Now my question is what is the Maximum Baud Rate usable ? PBP manual says that for SEROUT2 oscillators greater than 4MHz may be required for more than 4800bps.
