between the microcontroller and the CS5463 are removed and the GUI software can not access the
CS5463 registers and functions.
The EEPROM must be programmed prior to the auto-boot sequence. When the CDB5463U Evaluation
Board is sent from the factory, the EEPROM is programmed with the following CS5463 command/data
sequence:
1. Write Mode register, turn high-pass filters on :
0x64 0x00 0x00 0x60
2. Unmask bit #2 (LSD) in the Mask register :
0x74 0x00 0x00 0x04
3. Start continuous conversion :
0xE8
4. Write STOP bit to Control register, to terminate auto-boot sequence :
0x78 0x00 0x01 0x00
This sequence programs the CS5463 for continuous conversion mode. If voltage and current signals are
applied to the inputs, the CS5463 will issue pulses on the E1 pin. See the CS5463 data sheet for more
details on auto-boot.
