A standard SPI device will have a MISO pin, a MOSI pin, an SCLK pin, and a SS pin. It has a data register that functions as a shift register.
Initially, suppose that Master has bits 1010 0011 in its shift register, and the slave has bits 0101 1100 in its shift register:
I want to know which bit (first MSB or first LSB) the master transfers to the slave first.
What will be the voltage on MOSI and MISO pin if the master transfer the first LSB ?
