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
Infinite Zero Detect Mute Control
This bit is Read/Write.
Default Value: 0
The INZD bit is used to enable or disable the Zero Detect Mute function described in the Zero Flag and Infinite
Zero Detect Mute section in this data sheet. The Zero Detect Mute function is independent of the Zero Flag
output operation, so enabling or disabling the INZD bit has no effect on the Zero Flag outputs (ZERO1-ZERO6,
ZEROA).
DAC Operation Control
where x = 1-6, corresponding to the DAC output V
These bits are Read/Write.
Default Value: 0
The DAC operation controls are used to enable and disable the DAC outputs, V
DACx = 0, the output amplifier input is connected to the DAC output. When DACx = 1, the output amplifier
input is switched to the DC common-mode voltage (V
