LIS3DH单击中断的方法是什么

数据手册没有明确提及在读取CLICK_SRC寄存器时强制此中断锁存和清除的方法（如INT1_CFG寄存器可以）。


应用笔记AN3308规定可以通过设置TAP_CFG寄存器中的LIR位来实现此行为。但是，数据表中未记录此位。另一个类似的部分也许？

我看到中断保持CLICK_LATENCY周期的持续时间如预期，但我希望尽快清除这一点，因为我在同一行使用数据就绪信号。有什么我可以做到的吗？我以相当低的数据速率（10hz）进行采样，因此缩短延迟时间不是一种选择。我正在使用没有INT2连接的OEM板。

The data sheet makes no explicit mention of a way to force this interrupt to latch and clear when the CLICK_SRC register is read (like the INT1_CFG registers can).


App note AN3308 states that this behavior can be achieved by setting the LIR bit in the TAP_CFG register.  However, this bit is not documented in the data sheet.  Another, similar part perhaps?  

I'm seeing the interrupt hold for the duration of the CLICK_LATENCY period as expected but would like to clear this sooner as I'm using the data ready signal on the same line.  Is there anything I can do to accomplish this?  I'm sampling at a fairly low data rate (10hz) so shortening the latency period is not an option.  I am using an OEM board that does not have INT2 hooked up.
