Well , I dunno.
Yeah actually we we can have one switch to like uh switch on , on and off , this  processor and  This really  , suppose like here we have our main chip which controls power , volume and this part and this D_S_P_s.
Mm-hmm.
Again , this to have some interaction like suppose people use D_S_P_ then it particularly sends some information to the chip like in some form , like volume and  like this key.
