Note: When using the SPI serial interface the register address bit A7 is also used for selecting write (A7= 0) or read (A7=1) operation. For

the I2C interface address bit A7 = 1.

Important note: All addresses presented in this document use 8-bit notation. The I2C bus device address

addresses start with MSB bit (A7) which selects between write (MSB=0) and read (MSB=1) and which is followed

by 7 address bits. For example when using 8-bit address notation the Configuration register write and read

one (A7=1).
