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.
Note: The programmable I2C device address register C2HEX has been factory programmed to value EC HEX (%11101100) which is the
same as the hard wired device address of MAS6512. When unique device address is needed it can be programmed to this register.
