器件型号：AM623工具与软件：
您好、TI 专家！
我有 AM6234的开发环境、其中包含我们自己的评估板。
软件 SDK 版本是 SDK-AM62X-08.06.00.42 PROCESSOR-SDK-LINUX-RT。
我想问一下、 在使用以下 API 时、我是否可以为 write_host 字段指定多个写入主机？
https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/am62x/hosts.html#enumeration-of-host-ids
如？所示、在写入外部 OTP 电子保险丝时、WRITE_HOST 字段可以设置为两个主机、例如 ID 为11和35 μ F 的主机
如果可能、如何修改以下代码？
