PIC10F200 Breakout Board - Use ICSPDAT and ICSPCLK as GPIOs?
Yes, you can use them as GPIOs. There are a few caveats though:


What you connect to the CLK and DAT pins in the way of other devices could interfere with the programming. You should include some way to isolate those devices if needed.
If you disable the MCLR functionality you can only use HVP mode for programming (not sure off hand if that chip does LVP or not). The >10V pulse on MCLR to enter programming mode could fry whatever is connected to it. Again you should provide some method to isolate that pin or otherwise mitigate that pulse (without interfering with the programming).
