The EEPROM must be programmed prior to the auto-boot sequence. When the CDB5460AU Evaluation
Board is sent from the factory, the EEPROM is programmed with the following CS5460A command/data
sequence:
This sequence programs the CS5460A for continuous conversion mode. If voltage and current signals are
applied to the inputs, the CS5460A will issue pulses on the EOUT pin. See the CS5460A data sheet for
more details on auto-boot.
