Expand description

@brief Writes a required count of bits as “1” to EFUSE field.

If there are no free bits in the field to set the required number of bits to “1”, ESP_ERR_EFUSE_CNT_IS_FULL error is returned, the field will not be partially recorded. After the function is completed, the writing registers are cleared. @param[in] field A pointer to the structure describing the fields of efuse. @param[in] cnt Required number of programmed as “1” bits.

@return

  • ESP_OK: The operation was successfully completed.
  • ESP_ERR_INVALID_ARG: Error in the passed arguments.
  • ESP_ERR_EFUSE_CNT_IS_FULL: Not all requested cnt bits is set.
