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.

same as the hard wired device address of MAS6503. When unique device address is needed it can be programmed to this register.
