Description
Bit 15
Control/
Data
When set high, it signifies a control word in Program or Mixed Program/Data Modes. When
set low, it signifies a data word in Mixed Program/Data Mode or an invalid control word in
Program Mode.
Bit 14
Read/
Write
When set low, it tells the device that the data field is to be written to the register selected by
the register field setting provided the address field is zero. When set high, it tells the device
that the selected register is to be written to the data field in the input serial register and that
the new control word is to be output from the device via the serial output.
Bits 13–11
Device Address
This 3-bit field holds the address information. Only when this field is zero is a device se-
lected. If the address is not zero, it is decremented and the control word is passed out of
the device via the serial output.
Bits 10–8
Register Address
This 3-bit field is used to select one of the eight control registers on the AD73322.
Bits 7–0
Register Data
This 8-bit field holds the data that is to be written to or read from the selected register
provided the address field is zero.
