Trouble clearing the interrupt pin on the H3LIS100 accelerometer chip.

Hi, I'm having some difficulty clearing the interrupt pin on the H3LIS100. I have it set to generate and interrupt on data ready. I am also using the LIS2D chip, which has a somewhat similar interface, and I can clear that interrupt by reading the INT1_SRC register (for an over threshold interrupt), but neither reading the INT1_SRC nor the actual data registers seems to clear the interrupt pin for the data ready interrupt condition on the H3LIS3100 chip. Going to power down state does clear the interrupt but that is not too useful when taking repeated data samples.
