I have been playing with Microchip's PICkit 1 and the 12F675 8-Pin PIC.  =
I have been using the internal RC oscillator, as it keeps the number of =
external parts down, which keeps the playtime with the PIC up.  I have =
downloaded and read the documentation on the device and am confused by =
trying to figure out what the clock cycle time is.

What I think I know;

-The documentation says that the minimum cycle time is 200nS which is a =
5MHz Clock
    -a 20MHz crystal used an external oscillator, would be divided by 4, =
in fact any external oscillator would be divided by 4
-the internal RC oscillator runs at ~4MHz, within 1% accuracy when =
calibrated.
    -the internal oscillator is not divided by 4, thus instruction cycle =
time is 250nS

Is this correct?  I understand some instructions may take 2 cycles to =
run.  Loops I have made appear to support that the internal RC =
oscillator is not divided by 4, but the documentation is not clear on =
this.

Thanks
  Andrew
