2.4.8 Control Register
The Control Register box contains various bits used to activate or terminate various features of the
CS5463. Refer to the CS5463 data sheet for descriptions of the bits. The user is able to turn each bit on
or off individually. The value of the Ctrl register is displayed in the HEX: field. Most of the Ctrl register bits
are reserved or unused. Only the usable bits are displayed in the Setup window.
2.4.9 Operational Modes Register
The Operational Modes Register box contains various bits used to set different operation modes for the
CS5463 functions. Refer to the CS5463 data sheet for descriptions of the bits. The value of the Mode reg-
ister is displayed in the HEX: field. Many of the Mode register bits are reserved or unused. Only the usable
bits are displayed in the Setup window.
2.5 Calibration Windows
The Calibration window is used to display and write to the CS5463 offset and gain calibration registers.
The user is also able to initiate the CS5463's calibration sequences that are used to set the calibration
values. Both AC and DC calibrations can be performed for offset and gain, for either the voltage channel
or the current channel, or both simultaneously. The user should refer to the CS5463 data sheet for more
details on calibration.
The Refresh Screen button will update the contents of the screen by reading all the register values from
the CS5463. It is a good idea to press the Refresh Screen button when entering the Calibration window,
or after modifying any registers to reflect the current status of the CS5463.
