I am trying to use SPI interface to have my ATMEGA8 acting a master to the TC77 temperature sensor, which supports SPI but only has 3 pins. They are: SCK, /CS, and SI/O. It does not have the MOSI/MISO pins separately.
How would I connect my ATMEGA8 to the TC77 to support SPI communication? Both ATMEGA8's MOSI and MISO pins connected to the TC77's SI/O pin?
