Darrel Taylor - Instant Interrupts-Problem 16F877A

[Darrel Taylor]

ENABLE and DISABLE have no effect with DT_INTS.
Those are only for ON INTERRUPT.

With DT_INTS there are two commands ...

@  INT_ENABLE  TMR1_INT
@  INT_DISABLE  TMR1_INT

They can be used anywhere in your program.
Once disabled, you will not receive any interrupts from that source or peripheral until you execute another @ INT_ENABLE.

When you INT_ENABLE, the flag is automatically cleared so you don't get an interrupt immediately if the flag was set.

Thanks for the quick relply, just some last bit of confusion left:
1) When interrupt will happen while waiting for an RF signal - How do I send the code to go from ISR to main label?

2) Can I disable the interrupt in the ISR? for eg:

_ToggleLED:
@INT_Disable
goto main
@INT_Return ' Should I use this if I am sending the code to another label?

How do I send the code to go from ISR to main label?

Like I said before.
You should NOT jump out of an interrupt handler to the main loop.

Hello Darrel
I am using the interrupts on 12F635 for a different program now and I am getting the following errors:

Any advise as to how to get rid of these?
I am trying to put interrupts for getting proper timeout for Serin command, is it a good way to it? Thanks for your help.
