SMBAlert output device address
The alert response function is
available when this register is cleared
(0x00) only.
When the several devices assert the
alert signal at the same time, the least
address is stored to this register. And
when this register is cleared , next
alert address is stored to this register.

To clear the notified event flag
without unexpected event loss, clear
the corresponding bit flag only.
For this operation, this register has
special writing manner as follows.
