The internal EEPROM of the CDCE706 is preprogrammed with a factory-default configuration as shown in

Figure 13. This puts the device in an operating mode without the need to program it first. The default setting

appears after power is switched on or after a power-down/up sequence until it is reprogrammed by the user to a

different application configuration. A new register setting is programmed via the serial SMBus Interface.

A different default setting can be programmed on customer request. Contact a Texas Instruments Sales and

Marketing representative for more information.
