Part Number: LMK03318
Using Lmk03318 I2C communication write block register data, but needed every to program on power ON, Trying to write EEPROM write function but write is not happening and PLL also not Locking, PLL also need to Lock, but required register i am setting, kindly let me know any example or possible solution for my problem
Hi Swathi,
Can you share with me the hex.txt or the .tcs files? I'd like to review your config to understand the PLL lock issue
To write the EEPROM per datasheet section 10.5.5, you'll first need to make sure that the Write SRAM procedure was done as to commit the register settings to SRAM. following that you'll write R144 with 0xEA, R137 bit 0 with 1. Once you've done these steps R136 will increment by 1, this contains the total number of EEPROM programming cycles that have been completed successfully. Then write R144 to 0.
If R137 bit 5 readback was 1, that means that the EEPROM write was unsuccessful, and the device will be locked and will not operate properly and you'll have to do another EEPROM write sequence and should be initiated and successfully completed to unlock the device.
Best,
Sandra
