STATUS REGISTER
The Status Register is a read only register. This register contains any fault information as a well as a RAMP ACTIVE bit and a User Toggle
Bit. By setting the STATREAD bit in the Main Control Register, the Status Register contents can be readback on the SDO pin during every
write sequence.

Description
This bit will be set if a fault is detected on DACA I
This bit will be set if a fault is detected on DACB I
This bit will be set if a fault is detected on DACC I
This bit will be set if a fault is detected on DACD I
This bit will be set if a fault is detected on DACA V
This bit will be set if a fault is detected on DACB V
This bit will be set if a fault is detected on DACC V
This bit will be set if a fault is detected on DACD V
This bit will be set while any one of the output channels are slewing (slew rate control enabled on at least one
channel)
This bit will be set if the AD5755-1 core temperature exceeds approx. 150°C.
Denotes a PEC Error on the SPI Interface Transmit.
DC-DC Failure on Channel A. This fault indicates that the DCDC is not operating, for example if the boost inductor is
not connected.
DC-DC Failure on Channel B. This fault indicates that the DCDC is not operating, for example if the boost inductor is
not connected.
DC-DC Failure on Channel C. This fault indicates that the DCDC is not operating, for example if the boost inductor is
not connected.
DC-DC Failure on Channel D. This fault indicates that the DCDC is not operating, for example if the boost inductor is
not connected.
User Writable bit that the user can set and readback while doing a Status Register read. This can be used to verify
data communications if needed.
