THS_P_L (0Ch)

User-defined threshold value for pressure interrupt event (Least significant bits) (R/W)

The threshold value for pressure interrupt generation is a 15-bit unsigned right-justified

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

THS_P (15-bit unsigned) = Desired interrupt threshold (hPa) x 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.
