are displayed in the “Last Conversion” box, as well as the Channel and Overflow indicator bits for each

conversion. The software will halt the data collection process when the user selects the Stop button.

Configuration Register: In the Configuration Register box, the contents of the Configuration Register are

displayed, and can be modified by typing a hexadecimal value in the Hexadecimal: box, or by changing

any of the values below the Hexadecimal: box to the desired settings. Note: When changing the value of

the reset system bit to ‘1’ (RS, bit 29 in the Configuration Register), the part will be reset, and all registers

will return to their default values. It is a good idea to select the Update Registers button after performing

a reset to update the screen with the new register values.

Channel Setup Registers: In the Channel Setup Registers box, all four Channel Setup Registers are dis-

played in hexadecimal. These registers can be modified from the Channel Setup Register Window, which

is accessed by selecting the Edit CSRs button.

Channel Setup Register Window: In the Channel Setup Register Window (Figure 6), each of the four

CSRs can be decoded and modified. The blue box at the top of the window allows the user to switch be-

tween CSRs. Each 32-bit CSR contains two 16-bit “Setups” which are decoded in the two boxes below

the hexadecimal value. The currently displayed CSR can be modified by either typing a value directly in

the Hexadecimal: box or by changing the decoded values in the individual Setup boxes.

Offset / Gain Registers: In the Offset Registers / Gain Registers box, the offset and gain registers for all

channels are displayed in hexadecimal. These registers can all be modified in the Calibration Window,

which is accessed when the user selects the Calibration Window button.

Calibration Window: The Calibration Window (Figure 7) permits the user to access the calibration reg-

isters for each channel of the CS5534 and also perform self and system offset or gain calibrations on any

of the channels. Prior to performing calibrations however, the Channel Setup Registers should be modi-

fied to configure the part for the desired operating mode (see the section on the Channel Setup Register
