PAUSE and ASM interruots

[MikeBZH]

Hi Alain,

Thank you for your answer which is perfectly clear.

About the context :

I have a permanent repetitive loop which successively calls several subs, always in the same order. This loop, wrotten in PBP, is periodically interruoted by an ASM program, There is no relation between the loop and the interrupt frequencies. Loop : about 2.5 kHz, interrupt : about 60 kHz.

I want to slow down this loop so the simplest way would be to add some PAUSE inside. So my question was: "What occurs if an interrupt comes when a PAUSE is being executed".

The loop duration is not critical at all, so the behaviour you describe should be appropriate.

Thank you for your help

Pause is a PicBasic command.

This command can be interrupted just fine with an ASM interrupt. But you have to be careful to save and restore critical registers during the ISR execution.

The problem is evident in PicBasic On Interrupt system, because the Basic Interrupt will be executed after Pause has finish.
