Important notice for interrupts

[zristic]

Bug ID: #050530001
Submitted by: zristic

Severity: Major
Status: Resolved, to be implemented since the version 3.0.0.4.

Description:
Using interrupts on P16 for codes over 2K causes unpredictable behaviour of program.

Workaround:
Make sure this instruction is the first one in the interrupt routine:

Code: Select all

PCLATH := 0;

Compiler should clear the register itself, but the implementation was omitted by mistake.
