PIC 12F675 bandgap settings

[dideco]

Dear friends,

I searched internet about bandgap reference settings and found only one site http://sprut.de/electronic/pic/grund/bandgap.htm but in German language.

I wonder what is it used for? I have some PICs (12F675) which have deleted GP1 and GP2 settings. Is there a way to find the correct setting?

Thanks in advance

I prefer AN250.pdf files Microchip sites. Why. How way take the OSCCAL calibration pdf files. And maybe use 3470 other 3490 and out osc pin internal osc fallow outside the pin with osc. This 3490 code you write last adress program memory. And then try it maybe reach nearly.
