标题: VL53L0X激光传感器芯片VL53L0X_GetInterruptMaskStatus接口失败，有人遇到相同的问...
代码加打印：
VL53L0X_Error VL53L0X_GetInterruptMaskStatus(VL53L0X_DEV Dev,
        uint32_t *pInterruptMaskStatus)
{
        VL53L0X_Error Status = VL53L0X_ERROR_NONE;
        uint8_t Byte;
        LOG_FUNCTION_START("");

        Status = VL53L0X_RdByte(Dev, VL53L0X_REG_RESULT_INTERRUPT_STATUS, &Byte);
        *pInterruptMaskStatus = Byte & 0x07;

        printf("wangling 111 VL53L0X_GetInterruptMaskStatus status = %d, Byte = 0x%02x\r\n", Status, Byte);
        if (Byte & 0x18)
                Status = VL53L0X_ERROR_RANGE_ERROR;

        LOG_FUNCTION_END(Status);
        return Status;
}
打印结果：
wangling 111 VL53L0X_GetInterruptMaskStatus status = 0, Byte = 0x48
进入了异常流程：
if (Byte & 0x18)
                Status = VL53L0X_ERROR_RANGE_ERROR;
