器件型号：TPS389006-Q1 主题中讨论的其他器件： TDA4VH、 TPS389006
工具与软件：
您好、TI：
我们正在使用 TPS389006-Q1、这款基于 TDA4VH 的定制电路板
TPS389006-Q1可通过 I2C 总线进行访问、但启用通道存在问题。
我们在激活 VMON4通道或6个通道中的任何一个时遇到了问题。
具体步骤如下：
- 选择组1
- 读取值(我们得到0x00)
- 写入值(我们写入0x08)
- 读取写入值(我们得到0x00)
- 所以、这就是写入的值存在问题的原因。 我们如何解决这个问题？
该日志包含检查存储体选择和写保护的附加步骤。

请注意、在日志中、我们有两个 TPS389006-Q1实例、两者的行为相同。
我们相信处于活动状态：ACT 和 SLEEP 都将配置为 HW 为高电平、 VMON_STAT 寄存器显示该状态。
此致、
Milena
