2.2.1.2 Window
After the user selects the appropriate setup, the Window option becomes available in the Start-Up win-
dow. The Window pull-down has three options: Start-Up Window, Setup Window, and Data Collection
Window.
2.2.2 Setup Window
The Setup Window allows the user to access the internal registers of the CS5534. See Figure 5.
Figure 5. CDB5534U Setup Window
In the Setup Window, all of the ADC’s registers are displayed as hexadecimal values. The Configuration
Register’s settings are also defined in this window.
Update Registers: The Update Registers button will read all the register values from the CS5534 and
update the hexadecimal values displayed on the screen. It is a good idea to press the Update Registers
button when entering the Setup Window, or after modifying any registers to reflect the current status of
the part.
Reset Serial Port: When this button is selected, the software will send the synchronization sequence dis-
cussed in the CS5534 datasheet to the ADC. This sequence brings the CS5534’s serial port back to the
command mode, but does not reset any of the registers in the part.
Reset Part: When this button is selected, a ‘1’ is written to the RS bit in the Configuration Register to reset
the part. After a reset, the registers will all return to their default values as discussed in the CS5534
datasheet.
Read Data: This button will instruct the ADC to begin performing repeated single (fully-settled) conver-
sions on the setup channel specified by the Setup Register box. The results of the most recent conversion
