Hi....

Help !!!!

Have just ported a program fom 16f628 to 16f818 but nw it wont go....
reason for porting was needing faster clock speed 818 can go at 20Megs 628 only 4 !

having spent morning getting nowhere thought I would blink an LED... Easy !!

No Joy.... So somthing wrong with my config. But what ???

INC File :- I am using MPASM!
