Any changes made to the configuration parameters on

the Overview tab result in a corresponding change in

the MAX6876 configuration registers for the connected

MAX6876 EV kit. If configuration changes are made

and no MAX6876 EV kit is connected, a warning dialog

box will appear. Any changes made while disconnect-

ed are lost when connection is established.

Advanced Tab

The Advanced tab provides a detailed indication of the

current Register Values in a table format. Values can

be changed by selecting the appropriate field with the

mouse cursor. Values are shown for both the volatile

configuration registers and the corresponding non-

volatile EEPROM locations. Figure 2 shows the appear-

ance of the Advanced tab for a typical configuration.

Configuration register values can be stored in the con-

figuration EEPROM by clicking on the Commit

Configuration button. Clicking the Locked checkbox

disables both register and EEPROM writes by setting

bit 2 of register 13h. To lock the EEPROM values, set

bit 2 of EEPROM location 33h.

Note: To unlock the EEPROM, first clear bit 2 of config-

uration register 13h, then clear bit 2 of EEPROM loca-

tion 33h.

The Input Pin’s State box allows software remote con-

trol of the logic-level voltage applied by the CMOD232

module to the MARGIN, ENABLE, and MR pins of the
