Register Map
The mode control register map is shown in Table 3. Registers 16–21 include an R/W bit, which determines whether a
register read (R/W = 1) or write (R/W = 0) operation is performed. Registers 22 and 23 are read-only.

R/W: Read/Write Mode Select
When R/W = 0, a write operation is performed.
When R/W = 1, a read operation is performed.
Default value: 0
ATx[7:0]: Digital Attenuation Level Setting
These bits are available for read and write.
Default value: 1111 1111b
Each DAC output has a digital attenuator associated with it. The attenuator can be set from 0 dB to –120 dB, in 0.5-dB steps.
Alternatively, the attenuator can be set to infinite attenuation (or mute).
The attenuation data for each channel can be set individually. However, the data load control (the ATLD bit of control register
18) is common to both attenuators. ATLD must be set to 1 in order to change an attenuator setting. The attenuation level
can be set using the following formula:
Attenuation level (dB) = 0.5 dB
(ATx[7:0]
DEC
– 255)
where ATx[7:0]
DEC
= 0 through 255
For ATx[7:0]
DEC
= 0 through 14, the attenuator is set to infinite attenuation. The following table shows attenuation levels
for various settings:
