IIC interface
Adjustments for this board are performed by the System Controller
via the IIC serial bus interface. This three wire bus interface
consists of a clock line, a data line and an interrupt line. The C/D
Board does not create any IIC interrupt. The following table lists all
adjustments performed via the IIC bus interface (I = Input to C/D
Board, O = Output from C/D Board):
