    Is it okay if I write these commands? (My logic is correct?)

    msb lsb
    i2cread SDA,SCl,% 1 101000 1 ,0,[H] ( BIT4=0, B2=0, B1=0, B0=0)
    i2cread SDA,Scl,%11010001,1,[M] ( BIT4=0, B2=0, B1=0, B0=1)

    and so on?

    I don't know what this bits do: MODE-POINTER-word, CONTROL-nibble (bits 8, 7, 6 and 5)
