I have an Atmega 128 and read the manual. On page 180 the information given does not include whether the transmission signal sent out of the TXD pin (3) is inverted or non_inverted. I know the default transmission settings are 8N1 9600 baud, but I need to verify if it is inverted or non_inverted. Also, If I use the chip for only transmission, do I need to ground the receive RXD pin (2) or do...

My problem is that the ADC is using a 3-wire SPI interface. I know that for using a 3-wire SPI interface MOSI and MISO need to be tied up. But I am not sure how can we do that. I would really...
