LIS3DE与LIS3DH硬件FIFO怎么处理

你好，
我们一直在开发板上使用LIS3DH并已切换到原型的LIS3DE。我们使用HW fifo功能批量读取传感器的值。 LIS3DE只有8位，因此我期望HW fifo只提供8位值，但似乎它仍然每个轴发送2个字节，这是正确的吗？
我问的原因仅仅是因为LIS3DE上不存在_L和_H的区别，我总是从寄存器0x29（而不是0x28）读取并使用自动递增读取。在接收到的数据中，每秒的值为零，因此这些值实际上是16位值的符号？
解释这些价值观的正确方法是什么？附：使用HW fifo功能从LIS读取的缓冲区

Hello,
we've been using the LIS3DH on a development board and have switched to the LIS3DE for the prototype. We're using the HW fifo feature to batch-read values from the sensor. The LIS3DE is only 8-bit and thus I was expecting the HW fifo to only provide 8-bit values, but it seems like it is still sending 2 bytes per axis, is this correct?
The reason I'm asking is simply due to the fact that the _L and _H distinction does not exist on the LIS3DE, I'm always reading from register 0x29 (instead of 0x28) and read using auto-increment. In the received data every second value is zero and thus the values are actually signed 16 bit values?
What is the correct way to interpret the values? Attached: Buffer as read from LIS using HW fifo feature
