CDB5460AU
DS487DBU1 7
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:
1. Set Configuration Register, turn high-pass filters on, set K = 1:
0x40 0x00 0x00 0x61
2. Set Pulse_Rate Register to 1000 Hz:
0x4C 0x00 0x7D 0x00
3. Set (Unmask) bit 2 (LSD) in the Mask Register:
0x74 0x00 0x00 0x04
4. Start continuous conversion:
0xE8
5. Write STOP bit in Control register, to terminate auto-boot sequence:
0x78 0x00 0x01 0x00
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.
