Own Address
This register contains the address that is used for slave
mode operation. If the first byte of transmission matches
this bit pattern, then the AAS bit in the Two-Wire Serial
interface 0 Control/Status register (0xFD01/0xFD03) will
be made active. Note that the data in this register is
shifted by one bit for comparisons, as the read/write bit is
transmitted along with the slave address. This register
should be programmed even if slave mode is not
supported by the firmware. If this register is not
programmed to a value other than zero, then the interface
will be in a monitor state and will only provide bus status.
