Table 9. Internal pin status

Pin #

Name

Function

Pin status

SCL

SPC

I²C/MIPI I3C® serial clock (SCL)

SPI serial port clock (SPC)

Default: input without pull-up

SPI/I²C/MIPI I3C® mode selection

1: SPI idle mode / I²C/MIPI I3C® enabled

0: SPI enabled / I²C/MIPI I3C® disabled

Default: input with internal pull-up

SDO

SA0

Serial data output (SDO)

I²C less significant bit of the device address (SA0)

Default: input without internal pull-up

SDA

SDI

SDO

I²C/MIPI I3C® serial data (SDA)

SPI serial data input (SDI)

3-wire interface serial data output (SDO)

Default: (SDA) input without internal pull-up

Internally not connected. Can be tied to Vdd, Vdd_IO, or GND.

GND

0 V supply

RES

Connect to GND if not used as interrupt pin 1(1)

GND

0 V supply

Vdd

Power supply

Vdd_IO Power supply for I/O pins

INT2

Interrupt pin 2. Clock input when selected in one-shot mode.

Default: input with internal pull-down(2)(3)

INT1

Interrupt pin 1

Default: input with internal pull-down(4)(5)

1. When the INT1_ON_RES bit of register CTRL1 (10h) is set to 1, the interrupt signals configured on the INT1 pin are routed to the RES pin.

2. The internal pull-down can be disconnected by setting the PD_DIS_INT2 bit of register PIN_CTRL (0Ch) to 1. When this is done, the INT2

pin needs to be externally biased.

3. The INT2 pin is configured as "push-pull output forced to GND" (and the internal pull-down disabled) as soon as it is configured with

the interrupt configuration bits in the CTRL3 (12h), MD2_CFG (20h), EMB_FUNC_INT2 (0Eh), FSM_INT2 (0Fh), and MLC_INT2 (11h)

registers.

4. The internal pull-down can be disconnected by setting the PD_DIS_INT1 bit of register PIN_CTRL (0Ch) to 1. When this is done, the INT1

pin needs to be externally biased.

5. The INT1 pin is configured as "push-pull output forced to GND" (and the internal pull-down disabled) as soon as it is configured with

the interrupt configuration bits in the CTRL2 (11h), MD1_CFG (1Fh), EMB_FUNC_INT1 (0Ah), FSM_INT1 (0Bh), and MLC_INT1 (0Dh)

registers.
