REGISTER DEFINITIONS
R/W
Read/Write Mode Select
When R/W = 0, a Write operation is performed.
When R/W = 1, a Read operation is performed.

6, has a digital attenuator associated with it. The attenuator may be
set from 0dB to –63dB, in 0.5dB steps. Alternatively, the attenuator may be set to infinite attenuation (or
mute).
The attenuation data for each channel can be set individually. However, the data load control (ATLD bit of
Control Register 7) is common to all six attenuators. ATLD must be set to ‘1’ in order to change an
attenuator’s setting. The attenuation level may be set using the formula below.
Attenuation Level (dB) = 0.5 (ATx [7:0]
