-The ICE Slave boards have various Event Functions -- actions to perform when they get an Event. Each action will listen to an Event Address from 0 through 7, where 0 is a no-action state.
+The ICE daughter boards have various Event Functions -- actions to perform when they get an Event. Each action will listen to an Event Address from 0 through 7, where 0 is a no-action state.
 The 4 Event Lines consists of 3 address lines and one 'Go' command. When the 'Go' wire goes high, each Slave board decodes the 3 address lines to determine the Event Address (0-7). If the address matches an address that an Event Function is listening on, then that function is run. If the address is 0, the event is ignored.
