3.2.6.5 Side Controls
The side controls include three programmable, momentary, pushbutton switches (Side Button 1
[SB1], Side Button 2 [SB2], Top Side Button [MON]) and a Push-To-Talk switch [PTT]. These
components interface to the expansion board via connector J2005 through a two-piece, bonded flex
circuit. A board-to-board connection routes the side controls signals from expansion board connector
P2001 to connector J4001 of the controller board. See
pin assignments.
Side button 1 (R266), side button 2 (R268) and the top side button (R135) are inputs to the CPLD
and are biased to 1.875V. A button press is detected when the OMAP reads a 'LO' state from the
CPLD EMIFS interface. PTT (R265) is connected directly to OMAP and a button press is detected
when a LO state is read.
