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)

1. I3C_DISABLE bit disables the MIPI I3CSM communication protocol.

Disable MIPI I3CSM interface. Default value: 0

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

I2C_DISABLE(2)

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

Disable I²C interface. Default value: 0

(0: I²C enabled; 1: I²C disabled)
