ACB Register Map
ACB Serial Data Register (ACBnSDA)
The ACBnSDA register is a shift register used to transmit and receive data. The most significant bit is transmitted (received)
first and the least significant bit is transmitted (received) last. Reading or writing to the ACBnSDA register is allowed only
when SDAST in ACBnST register is set or for repeated starts after setting the START bit. An attempt to access the register
in other cases may produce unpredictable results.
