e524.33烧写eeprom

Question

The procedure for adjusting the frequency should be as following:

1. Set F_DRV according to the desired frequency with 'CALIB_WRITE'.
2. Measure the current frequency with 'CAL_PULSES'.
3. Calculate the percental difference between target frequency and current frequency.
4. Choose value for OSC_TRIM according to Table 6.3.1-1.
5. Repeat until the target frequency is reached.
6. Store the setting for OSC_TRIM by the 'EE_COPY' command.
   When 'CALIB_WRITE' is used to tune the frequency fOSC the value of OSC_TRIM is valid for the next measurement and stays in the register. If the EEPROM is programmed with 'EE_COPY' the value of OSC_TRIM is taken over into the EEPROM and the OSC_TRIM register is set to 0 again.
   为什么烧写完EEPROM后，OSC_TRIM register又被设置为0 呢，校准用的不是寄存器中的值吗

Answer 1

Follow the recommended F_DRV value for your desired frequency in the datasheet to adjust it in the EEPROM.
