Slave Device Idle Array
The slave device idle array contains 64 bits of data. Each bit indicates the state
of a slave device. A bit value of 0 represents a Non-idle mode or that the slave
is not present in the scanlist. A bit value of 1 represents Idle mode where the
slave node is present in the scanlist.
