Hi.Frends.

I want to use F84 but in my Country ı can not find F84 SMD. So I decide F28 to use becouse ı can find F628 SMD easly.
But ı have a problem with f628 as follows:

I wrote the for F84 and I did necessery changing for F628 but code not working on F628.

Code sample for F628:

....
....
....
CMCON=7
VRCON=0

......
......
But it is not vorking. then:

CMCON =7

.....
.....

Not working.


Is there another way to need chamge or what Iam doing wronge.

If anybody helpme thanks alot!....
