Multi-Function Control Inputs S0 and S1

The CDC706 features two user definable inputs pins which can be used as external control pins or address pins.

When programmed as control pins, they can function as clock select pin, enable/disable pin or device

power-down pin. If both pins used as address-bits, up to four devices can be connected to the same SMBus. The

respective function is set in Byte 10; Bit [3:0]. Table 4 shows the possible setting for the different output

conditions, clock select and device addresses.
