HAL_FDCAN_GetRxFifoFillLevel() in HAL_FDCAN_RxFifo0Callback()

[JiriCep]

I would like to ensure that I can use HAL_FDCAN_GetRxFifoFillLevel() function in  HAL_FDCAN_RxFifo0Callback() like this:

void HAL_FDCAN_RxFifo0Callback(FDCAN_HandleTypeDef *hfdcan, uint32_t RxFifo0ITs)
{
  if (RxFifo0ITs & FDCAN_IT_RX_FIFO0_NEW_MESSAGE) 
  {
    // used loop to read all messages from FIFO
    while (HAL_FDCAN_GetRxFifoFillLevel(hfdcan, FDCAN_RX_FIFO0) > 0) 
    {
      can_msg_t rx_msg = {0};
      if (HAL_FDCAN_GetRxMessage(hfdcan, FDCAN_RX_FIFO0, &rx_msg.hdr, rx_msg.data) != HAL_OK)
      {
         break;
      }
      rx_msg.data.data_len = (uint8_t)dlc_to_bytes(rx_msg.hdrDataLength);
      // put rx msg to queue
      osMessageQueuePut(rx_queue_handle, &rx_msg, 0, 0);
    }
  }
}

When I googling more whether I can use HAL_FDCAN_GetRxFifoFillLevel() in ISR CalIback I got:

HAL_FDCAN_GetRxFifoFillLevel is not guaranteed to be ISR-safe because it's a read operation on a peripheral register that doesn't automatically handle atomic operations, which are required in interrupt contexts to prevent data corruption from race conditions with the main application. To safely use it from an ISR, you must implement a mechanism to ensure the read operation is atomic, such as temporarily disabling interrupts or using a mutex if in an RTOS environment

I doubt it, is that correct?

Many Thanks.
