C15 are input buffers which read in the present state of the membrane keys Depressing a key causes the signal line to be pulled low in contrast to its normally high state Also located on the input buffer IC13 are the CAPNOSTAT CO2XDISC CO2ZERO and CO2SPAN signals which inform the system that a CAPNOSTAT sensor is disconnected if it is connected and currently on the Zero Cell or if it is connected and currently on the Reference Cell IC17 provides a latched output for controlling the membrane and Alert LEDs and the LCD backlight When the BACKLITE signal is pulled high IC17 pin 13 transistor Q5A turns on allowing maximum display brightness Otherwise the current through the display must also pass through fixed resistor R103 causing the display to dim Contrast control for the LCD is provided by DAC IC78 and amplifier IC77B schematic 2731 03 sheet 9 When the CPU detects the closure of the contrast membrane key the CPU sends a digital ramp input to the DAC which causes the its output to change accordingly Inverting amplifier IC77B controls the base current into transistor Q31 which changes the output of the display contrast voltage VDISP See page 7 To supplement the visual indicators associated with the membrane keypanel and display an audio output signal is generated to provide an additional mode to convey information to the user Up to three tone frequencies are generated by the TPU processor of the MC68332 DTOUTI DTOUT2 DTOUT T
