[PIC] PIC10F200 -- How does one get FOSC4 to output on GP2 ???

[userx2]

Hi
I am pulling my hair our here in frustration...


I have the non debug 8 pin version chip here, connected to an ICD3.

It seems to run code ok in that I can toggle GP1 and I also have the timer working.
The oscillator appears to be slow. I would like to verify this by measuring it on GP2.

I have tried everything I can think of but can't get GP2 to output the FOSC4. The pin just stays low, no matter what I try.
I have tried:

Nothing specific. -> No output

OSCCAL.0 = 1 -> No output
OSCCAL.0 = 0 -> No output
TRISGPIO = 0 -> No output
TRISGPIO = 0x2 -> No output

GP2 works ok as if I use it as an input and I am sucessfully using it.

Can someone please help me get that FOSC4 to come out on GP2?

Best regards
X

It should simply be a case of using OSCCAL.0 = 1 but check table 5-1 on the data sheet in case your program is re-allocating the pin function later.
