1. LockLost问题
   1. 配置如下

      # INTR_CTL_FPD4_PORT0 -> 使能IE_RX_LOCK_DET_INT & IE_RX_LOCK_LOST_DET_INT

      i2cwrite(0x40, 0x24)

      i2cwrite(0x41, 0x8c)

      i2cwrite(0x42, 0x48)

      # INTR_CTL_FPD4_PORT1 -> 使能IE_RX_LOCK_DET_INT & IE_RX_LOCK_LOST_DET_INT

      i2cwrite(0x41, 0x9c)

      i2cwrite(0x42, 0x48)

      # INTERRUPT_CTL -> 使能INTB_PIN_EN & DEVICE_INT_EN & IE_FPD_TX1 & INT_FPD_TX0

      i2cwrite(0x51, 0x8f)

      # 断开983-984之间线束连接

      # INTR_STS_FPD4_PORT0 -> 读取 IS_RX_LOCK_LOST_DET_INT -> 并无中断

      i2cwrite(0x40, 0x24)

      i2cwrite(0x41, 0x8d)

      i2cread(0x42)

      # INTR_STS_FPD4_PORT1 -> 读取 IS_RX_LOCK_LOST_DET_INT -> 并无中断

      i2cwrite(0x40, 0x24)

      i2cwrite(0x41, 0x9d)

      i2cread(0x42)

      # GENERAL_STS -> 读取LINK_LOST -> 可以读取到LINK_LOST flag，datesheet中提到的CRC ERROR RESET in register 0x04去手动clear该flag，但是datasheet中并无0x04 register

      i2cwrite(0x2d, 0x01)

      i2cread(0x0c)

      i2cwrite(0x2d, 0x12)

      i2cread(0x0c)

      # INTERRUPT_STS -> 读取GLOBAL_INT & DEVICE_INT & IS_FPD_TX1 & IS_FPD_TX0 ->并无中断status

      i2cwrite(0x2d, 0x01)

      I2cread(0x52)

      i2cwrite(0x2d, 0x12)

      I2cread(0x52)

2. LineFault问题
   1. 配置如下

      # Enable PORT0, PORT1 LINK_DETECT respectively -> 不确定这个是不是LineFault中断使能，没找到其他相关的

      i2cwrite(0x40, 0x24)

      i2cwrite(0x41, 0x88)

      i2cwrite(0x42, 0x01)

      i2cwrite(0x41, 0x98)

      i2cwrite(0x42, 0x01)

      # INTERRUPT_CTL -> 使能INTB_PIN_EN & DEVICE_INT_EN & IE_FPD_TX1 & INT_FPD_TX0

      i2cwrite(0x51, 0x8f)

      # 断开983-984之间线束连接

      #  LOCAL_INT_STS -> 读取INTERRUPT_LINE_FAULT -> 并无中断

      i2cwrite(0x2d, 0x01)

      i2cread(0x87)

      i2cwrite(0x2d, 0x12)

      i2cread(0x87)

3. ADC读取问题
   1. 配置

      # 使能ADC_INPUT_EN_TEMP

      i2cwrite(0x40, 0x38)

      i2cwrite(0x41, 0x07)

      i2cwrite(0x42, 0x01)

      i2cwrite(0x41, 0x08)

      i2cwrite(0x42, 0x00)

      # 使能ADC_MODE -> 使能之后，是可以多次读取ADC值，还是每次使能只能读取一次，多次读取ADC需要反复使能？是如何确定ADC转换完成的？

      i2cwrite(0x41, 0x0d)

      i2cwrite(0x42, 0x80)

             # 读取TEMP_FINAL -> 读取结果完全不对

      i2cwrite(0x41, 0x13)

      i2cread(0x42)

4. LineFault 如何确认具体LineFault错误类型，看datasheet只是知道通过adc来判断，但是具体流程不明
5. 读取哪个内部故障寄存器，可以判断宕
