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
ZREV – Zero-Flag Polarity Select
Default value: 0
ZREV = 0
Zero-flag pins HIGH at a zero detect (default)
ZREV = 1
Zero-flag pins LOW at a zero detect
The ZREV bit allows the user to select the polarity of zero-flag pins.
DREV – Output Phase Select
Default value: 0
DREV = 0
Normal output (default)
DREV = 1
Inverted output
The DREV bit allows the user to select the phase of the analog output signal.
DMF[1:0] – Sampling Frequency Selection for the De-Emphasis Function
These bits are read/write.
Default value: 00b

Reserved
The DMF[1:0] bits are used to select the sampling frequency used for the digital de-emphasis function when it is
enabled. The de-emphasis curves are shown in the Typical Performance Curves section of this data sheet. The
preceding table shows the available sampling frequencies.
DMC – Digital De-Emphasis, All-Channel Function Control
This bit is read/write.
Default value: 0
DMC = 0
De-emphasis disabled for all channels (default)
DMC = 1
De-emphasis enabled for all channels
The DMC bits are used to enable or disable the de-emphasis function for all channels. The three DMC bits are
ORed together. Setting any one DMC bit, any combination of two DMC bits, or all three DMC bits to 1 enables
digital de-emphasis for all channels. Setting all three DMC bits to 0 disables digital de-emphasis for all channels.
