<h1>Pico commands</h1>

<h2>Enumerate notification</h2>
The enumerate command is a notification which set the announce bit in all the slave nodes. 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.
