Can I use serin2 on MCLR pin set up as a I/0 pin? Using a 12F683 with MCLR off.
Should be fine as long as you configure the pin as an I/O pin.
The weak pull up on that pin is disabled when you configure it as I/O, so depending on how the device sending the signal is set up, you may need to use a pull up resistor.
