IIC Address Register 2 (IICA2)
SMBUs Address — The AD[7:1] field contains the slave address to be used by the SMBus. This field is used on
the device default address or other related address
The value in this register is the most significant byte of SCL low time out value that determines the
time-out period of SCL low.
