19.1 SPI DATA INTERFACE
The device is programmable via 4-wire SPI Interface. The
signals associated with this interface are CS, DI, DO and CLK.
Through this interface, the user can enable/disable the de-
vice, program the output voltages of the individual Bucks and
of course read the status of Flag registers.
By accessing the registers in the device through this interface,
the user can get access and control the operation of the buck
controllers and program the reference voltage of the com-
parator in the device.
