The enumerate command can contain a filter condition with the following format: <object><register> op <value>object 6 bits containing the object number register 6 bits containing the register number in the object op 2 bits containing the operation (eq lt gt and) inv 1 bit inverting the comparation result rsv 1 bit reserved value 16 bits containing the value to compar
If a node doesn't support enumerate filters, the notifiction is ignored and no ACK bit is generated.
Otherwise, the slave should try to become master in the next election and should send an announce notification.
