    Initializing the variable works!

    Thanks!

    Perhaps your problem is one of initialization. Unless you explicitly clear that data structure it will contain random data except for the bits you set.

    setup_a_t setup_a;

    setup_a.value = 0;

    setup_a.bits.a = (uint8_t) 3;

    SPI_write_reg (REG, setup_a.value);
