THS_P_L (0Ch)

User-defined threshold value for pressure interrupt event (Least significant bits).

The threshold value for pressure interrupt generation is a 16-bit unsigned right-justified

value composed of THS_P_H (0Dh) and THS_P_L (0Ch).The value is expressed as:

Interrupt threshold (hPa) = ±THS_P / 16

To enable the interrupt event based on this user-defined threshold, the DIFF_EN bit in

INTERRUPT_CFG (0Bh) must be set to '1', the PHE bit or PLE bit (or both bits) in

INTERRUPT_CFG (0Bh) has to be enabled.

9.3

THS_P_H (0Dh)

User-defined threshold value for pressure interrupt event (Most significant bits).
