(B1h) USER_DATA_01 (COMPENSATION_CONFIG) can be written to while output conversion is enabled, but updating those values to hardware will be blocked. To update the value used by the control loop:
Due to the complexity of translating the 5-byte HEX value of (B1h) USER_DATA_01 (COMPENSATION_CONFIG) into analog compensation values, users are recommended to use the tools available on the TPS546D24S product folder such as the TPS546x24S Compensation and Pin-Strap Resistor Calculator design tool.
