你好雷，
为了给您答案，让我参考MCU
http://www.st.com/resource/en/datasheet/stm8s003k3.pdf
。这是正确的，来自Option Bytes区域的AFR7位负责蜂鸣器。但是，如果我们在上述文件中提到更详细的信息，我们可以注意到：在表14中，它描述了STM8S003K3的选项字节，AFR7是保留的。在表15中，它取消了STM8S003F3的选项字节，AFR7可以重新配置。如果我们使用STVP并在开始时选择STM8S003F3然后选择STM8S003K3，结果是相同的：STM8S003F3允许改变AFR7的值而STM8S003K3不允许改变AFR7。
因此，没有什么不对，你做的。您使用的潜水装置不支持此功能。
问候

Hello Lei,
In order to provide you the answer, let me refer to MCU's
http://www.st.com/resource/en/datasheet/stm8s003k3.pdf
. This is correct, that AFR7 bit from Option Bytes region is responsible for beeper. However if we refer to more detailed information in mentioned document, we can notice that:
- in Table 14, which desribes Option Bytes for STM8S003K3, AFR7 is reserved.
- in Table 15, which desribes Option Bytes for STM8S003F3, AFR7 can be reconfigured.
If we use STVP and select at the beginning STM8S003F3 and then STM8S003K3, the result is the same: STM8S003F3 allows to change value of AFR7 and STM8S003K3 doesn't allow to change AFR7.
So as a result there is nothing wrong, which you do. Simply the diveice, which you use, doesn't support this feature.
Regards
Szymon
