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
OVER – Oversampling Rate Control
These bits are read/write.
Default value: 0
x
System clock rate = 256 fS, 384 fS, 512 fS, or 768 fS:
OVER = 0
64× oversampling (default)
OVER = 1
128× oversampling
x
System clock rate = 128 fS or 192 fS:
OVER = 0
32× oversampling (default)
OVER = 1
64× oversampling
The OVER bit is used to control the oversampling rate of the delta-sigma DACs. The OVER = 1 setting is
recommended when the oversampling rate is 192 kHz (system clock rate is 128 fS or 192 fS).
GPOE – General-Purpose Output Enable
This bit is read/write.
Default value: 0
GPOE = 0
General-purpose outputs disabled (default)
Pins default to zero-flag function (ZERO1 through ZERO6).
GPOE = 1
General-purpose outputs enabled
Data written to GPO1 through GPO6 appears at the corresponding pins.
GPOx – General-Purpose Logic Output
Where: x = 1 through 6, corresponding pins GPO1 through GPO6.
These bits are read/write.
Default value: 0
GPOx = 0
Set GPOx to 0 (default)
GPOx = 1
Set GPOx to 1
The general-purpose output pins, GPO1 through GPO6, are enabled by setting GPOE = 1. These pins are used
as general-purpose outputs for controlling user-defined logic functions. When general-purpose outputs are
disabled (GPOE = 0), they default to the zero-flag function, ZERO1 through ZERO6.
