7.14 Tone Generator
The programmable tone generator is capable of producing programmable tones.
Upon reception of the tone enable instruction, the Venture connects the output of
the tone generator to the input of the D/A converter. The programmed tone is then
output until a tone disable instruction is issued. When disabled, the normal audio
signal is again connected.
7.15 Cross Fader
To minimize potential loud transients when switching between memories, Venture
uses a cross fader block. When the memory is changed, the audio signal is faded
out, followed by the memory select indicator beeps (if enabled), and after switching
to the next memory, the audio signal is faded back in. The cross fader is also used
when turning the Tone Generator on or off, and during SDA programming.
7.16 Power-On/Power-Off Behavior and Low Battery Indicator
During power-on, the Venture hybrid is held in a reset state until the supply voltage
(Vb) reaches a turn-on threshold. A small portion of the hybrid's internal control
logic turns on and monitors the voltage to determine if the supply is stable. Once
the supply is stable, the entire hybrid is activated and loads its configuration.
Finally, the audio output turns on by smoothly transitioning to the expected output
level.
During normal operation, when a low battery condition (below turn on threshold) is
detected, the Venture hybrid sends out a series of one to seven beeps (each beep
is 512ms ON and 512ms OFF) to indicate the battery is low. This will repeat every
five minutes until the device reaches the turn-off threshold.
The low battery threshold is programmable in IDS between 1.0V and 1.2V in 10mV
increments.
If Vb drops below the turn-off threshold then the Venture hybrid is returned to its
reset state and the audio output is muted. After a reset due to a low battery or a
sudden supply transient, the recovery behavior of Venture is determined by the
selectable reset mode through ARKonline.
