Hi,
I am facing some problems in compiling hardware interrupts in PDS & the application is hanging repeatedly.In the help I find the following:
"the assembler code may be viewed in order to ascertain whether any system variables are being used. Some of these are: -
PP0, PP0H, PP1, PP1H, PP2, PP2H, PP3, PP3H, PP4, PP4H, PP5, PP5H, PP6, PP6H, PP7, PP7H, GEN, GENH, GEN2, GEN2H, GEN3, GEN3H, GEN4, GEN4H, GPR, BPF.
If an unrecognised or undeclared variable name is seen within the interrupt handler's assembler code, then it will be a SYSTEM variable, and the program may fail, either subtly or disastrously."
It is not clear whether they mean that these variables are allowed in the I.S.R.In my assembler code I find that these are present.
Can someone please help?
