Hi,
We would like to ask a question about CDCI6214.
We sometimes have issue not to be able to write EEPROM page value correctly.
Can you please check our programing procedure?
CDCI6214 Pin setting
- REFSEL:Low
- ROMSEL:High
Access flow is:
1.Power up CDCI6214
2.Apply RESETN=Low
3.Apply RESFEL=Low, EEROMSEL=High
4.Apply RESETN=High
5.USE I2C interface to configure the device using address 0x76
6.Prepare an EEPROM image consisting of 64 words
7.Unlock the EEPROM for write access with ee_lock 0x05
8.Write the initial address offset to the address bit_field. Write a 0x00 to nvm_wr_addr.
9.Loop through the EEPROM image from address 0 to 63 by writing each word from the image to nvm_wr_data.
10. power-down/up CDCI6214
Best regards,
