Table 28. IF_CFG register description

SDA_PU_EN

Enables pull-up on SDA pin. Default value: 0

(0: SDA pin pull-up disconnected;

1: SDA pin with pull-up)

SHUB_PU_EN

Enables master I²C pull-up. Default value: 0

(0: internal pull-up on auxiliary I²C line disabled;

1: internal pull-up on auxiliary I²C line enabled)

ASF_CTRL

Enables anti-spike filters. Default value: 0

(0: anti-spike filters are managed by the protocol and turned off after the broadcast address;

1: anti-spike filters on SCL and SDA lines are always enabled)

H_LACTIVE

Interrupt activation level. Default value: 0

(0: interrupt output pins active high;

1: interrupt output pins active low)

PP_OD

Push-pull/open-drain selection on INT1 and INT2 pins. Default value: 0

(0: push-pull mode;

1: open-drain mode)

SIM

SPI serial interface mode selection. Default value: 0

(0: 4-wire interface;

1: 3-wire interface)

I2C_I3C_disable

Disables I²C and MIPI I3C® interfaces. Default value: 0

(0: SPI, I²C and MIPI I3C® interfaces enabled;

1: I²C and MIPI I3C® interfaces disabled)
