PIC18F14K50 and PLL

[pebbert9]

I had a program that worked fine under 4.124 using a PC18F14K50.

I compiled it under 4.128 and it didn't work properly.

After a few hours of digging i noticed that the PLL wasn't being enabled under 4.128 even though it worked under 4.124 with the same code.

More digging and I stumbled on that if I changed my previous #use delay(crystal=12M) to #use delay(clock=12M) everything works as before.

Is this a bug or why wouldn't the PLL be enabled by using the "crystal" designation?

Note: #use delay(clock=12M, crystal) also doesn't work

If you have a crystal at 12M, and the CPU running at 12M, then the PLL has to be off.....
What has happened is that CCS have tightened things up.
So if you have the CPU running at 12MHz, you either have to say just this (clock=12M), and specify the PLL fuse yourself, or you have to specify both the clock frequency (clock=xxx), _and_ the crystal _frequency_ (not just crystal, but crystal=yyy), which then enables the PLL if needed to get that combination.
