Hi am using STM32F107VCT6 and found there is no IR_OUT, IR_IN pins and the same I/O lines found in STM32F072VBT6. Please suggest how to use IR_OUT, IR_IN pins in STM32F107VCT6 or not.  Thank you.

IR_OUT is just a NAND on two timer outputs, so you can replace it by an external NAND gate  (e.g. a 74HC00, checking its current drive capability).

I don't know where do you see IR_IN.
