and (important to understand), the only reason to do this, is if you have a handler that must be handled really quickly. In this case you only save the registers that are used in this handler, and get ...

It means you can't have #int_global and #int_rda (for example) at the

Hi ElectronPIC, the reason you don't want to disable the RDA Interrupt is basically, you have no control over when bytes of data will arrive at the receiver input and if you don't read in and process ...

re: WDT

WDT should be disabled until you're 100% confident your code is correct and 'market ready' THEN enable the WDT and see what happens....
WDT testing could easily take another week or 2.... ...

Thank you all for your answers!

I didn't actually look at your program before. I just read your symptoms
and thought of the usual solution.

I didn't look closely at your code, but here are s ...

Well, I've looked at the post and I think I'm doing the same thing to clear the buffer before enabling it. The problem persists. When I send a long string of commands, when I start receiving character ...

The UART has a 2-deep receive fifo and the incoming shift-register.
It will still load up with characters, even if you shut off interrupts.
To clear the buffer, see the clear_uart() macro by Ttelmah ...
