PRODUCTION DATA.
命令 = 11h,带 1 个数据字节,只读
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
AUTO | SLA4 | SLA3 | SLA2 | SLA1 | SLA0 | 0 | 0 |
AUTO 引脚 | A4 引脚 | A3 引脚 | A2 引脚 | A1 引脚 | 0/1(1) | 0 | 0 |
说明:R/W = 读取/写入;R = 只读;-n = 复位后的值 |
位 | 字段 | 类型 | 复位 | 说明 |
---|---|---|---|---|
7 | AUTO | R | AUTO | 自主模式启用位。
0 = 自主模式禁用(AUTO 引脚悬空) 1 = 自主模式启用(在 AUTO 引脚和 GND 之间配置了有效电阻) 注意:仅在较低的 I2C 寄存器集(通道 1-4)中设置该位。 |
6-3 | SLA4-SLA1 | R | 请参阅上文 | I2C 器件地址(使用引脚 A4-A1 时进行定义)。 |
2 | SLA0 | R | SLA0 位在内部定义为 0 或 1
0 = 通道 1-4 1 = 通道 5-8 |
