i am unable to understand the explaination of the following register I NT1_THS (32h) of LIS3DH chip?

[Kpawa.2]

Interrupt 1 threshold. Default value: 000 0000

1 LSb = 16 mg @ FS = ±2 g

1 LSb = 32 mg @ FS = ±4 g

1 LSb = 62 mg @ FS = ±8 g

1 LSb = 186 mg @ FS = ±16 g what is this ????? Please Help........

You can set a minimum threshold before an interrupt is raised. The threshold value in the register is a 7-digit binary number, proportional to the physical acceleration. The prop. factor is such that a value of 1 (the least significant bit, LSB) corresponds to x milli g (x times Gravity of Earth/1000).

x depends on the device sensitivity set. For FS = ±16 g (Full scale = 16 times Gravity of Earth) factor x is 186 milli g, and so on
