Low Level Configuration Page

The Low Level Configuration page, shown in Figure 3-8, allows access to low-level communication directly with the respective DACx3204 device registers. Select a register on the Register Map list to show a description of the values in that register, as well as information on the register address, default value, size, and current value. Data are written to the registers by entering a value in the value column of the GUI.

To store the values of the register map locally, select Save Configuration under the File menu option. The stored configuration files can be recalled and loaded by selecting Open Configuration.

Figure 3-9 shows the four configuration buttons provided on the Low Level Configuration page that allow the user to read from and write to the device registers:

  • Write Selected
  • Write Modified
  • Read Selected
  • Read All

The Write Modified button is enabled only in Deferred Update Mode. Deferred Update Mode initiates a write operation only when the Write Selected or Write Modified buttons are pressed. By default, Immediate Update Mode is selected for the Low Level Configuration page write operations.
