I2C Interface

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-

The basic timing is shown in the diagram below:

Figure 11 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:

Figure 12 I2C write and read commands

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:
