I2C Interface

The I2C slave interface is compatible with Philips I2C Specification version 2.1. The I2C interface supports

standard, fast and high speed mode.

The sensor's address is 0x77 (if SDO pin is left floating or pulled-up to VDDIO) or 0x76 (if the SDO pin is pulled-

down to GND). The I2C interface uses the pins described in Table 2

The basic timing is shown in the diagram below:

I2C timing diagram

In one access, without stop, incremental read (address is auto increment) and auto-incremental write is

supported. The read and write access is described below:

I2C write and read commands

6.2

SPI Interface

The SPI interface is compatible with SPI mode '11' ( CPOL = CPHA = '1'. The SPI interface has two modes: 4-wire

and 3-wire.

The protocol is the same for both. The 3-wire mode is selected by setting '1' to the register Interrupt and FIFO

configuration (CFG_REG)

The SPI interface uses the pins like in theTable 2 Refere toApplication Circuit Example for connections

instructions. The SPI protocol is shown in the diagram below:
