Bit 5 = Reserved, must be kept at 0.
Bit 4 = ITER BERR / NACK Interrupt enable
In case of error, if ITER is enabled either interrupt 1 or 2 is generated depending on which
slave flags the error (see
Bit 3= ITRE3 Interrupt enable on read from Slave 3
Bit 2 = ITRE1/2 Interrupt enable on read from Slave 1 or 2
