THS_P_L (0Ch)

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

THS7

THS6

THS5

THS4

THS3

THS2

THS1

THS0

THS[7:0]

This register contains the low part of threshold value for pressure interrupt generation. Default value: 00h

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.

9.3

THS_P_H (0Dh)

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

THS14

THS13

THS12

THS11

THS10

THS9

THS8

THS[14:8]

This register contains the high part of threshold value for pressure interrupt generation. Default value: 00h

Refer to THS_P_L (0Ch).

9.4

IF_CTRL (0Eh)

Interface control register (R/W)

INT_EN_I3C

SDA_PU_EN

SDO_PU_EN

PD_DIS_INT1

I3C_DISABLE

I2C_DISABLE

INT_EN_I3C

Enable INT1 pad with MIPI I3CSM. If the INT_EN_I3C bit is set, the INT1 pad is polarized as OUT. Default value: 0

(0: INT1 disabled with MIPI I3CSM; 1: INT1 enabled with MIPI I3CSM)

SDA_PU_EN

Enable pull-up on the SDA pin. Default value: 0

(0: SDA pin pull-up disconnected; 1: SDA pin with pull-up)

SDO_PU_EN

Enable pull-up on the SDO pin. Default value: 0

(0: SDO pin pull-up disconnected; 1: SDO pin with pull-up)

PD_DIS_INT1

Disable pull down on the INT1 pin. Default value: 0

(0: INT1 pin with pull-down; 1: INT1 pin pull-down disconnected)

I3C_DISABLE(1)

Disable MIPI I3CSM interface. Default value: 0

(0: MIPI I3CSM enabled; 1: MIPI I3CSM disabled)

I2C_DISABLE(2)

Disable I²C interface. Default value: 0

(0: I²C enabled; 1: I²C disabled)

1. I3C_DISABLE bit disables the MIPI I3CSM communication protocol.

2. I2C_DISABLE bit disables the I²C interface, by default both SPI and I²C interfaces are enabled.
