Well,

With the example given, Sure!

But with 16F's, if it gets more complicated, you might have problems. The problem is that when you have more than 1 interrupt source, the HSERIN will stop the others from happening while it waits for the data to come in. But if you only intend to use the one interrupt from the USART. No Problem.

If you were using an 18F with multiple INT sources, then the HSERIN could be in a Low Priority Interrupt without any problems at all.
