Hello I am very new to programming and I need to interface my STM32L011 with ISO 7816 -2 to send ATR commands. Kindly help me with that.

The ISO standard you list is an old protocol for board to board communication. It has been, essentially, discontinued because nobody uses high voltage Vpp (21v) for programming anymore. What are you trying to do? What are you connecting to your STM32L011?
