Timer interrupt 16F1827

[Macgman2000]

Hello Bruce, Darrel,

Thanks for your help! I read in the data sheet that the context saving is done automatically. So unlike
the 16F877A where a context saving routine example is featured, the 16F1827 does not have any
such routine listed in the data sheet. Just a few lines that mention automatic context saving.

So, using PBP do I need to use context saving using the ASM ISR ?

Nope. If you're using the 16F1827 you don't need to save w, status, bsr, fsr or pclath. It does this for you automagically...

OOPs, there's no FAST option on RETFIE with those chips.
It always restores them.
