GA3219 / GA3218 / GA3217 Preliminary Data Sheet
Proprietary and Confidential
32718 - 2
February 2005

In this mode it is possible to jump from any memory to any other memory simply by
changing the state of both switches. If both switches are changed simultaneously
then the transition will be smooth, otherwise, if one switch is changed and then the
other, the part will transition to an intermediate memory before reaching the final
memory.
When MS2 is set HIGH, the state of the switch on MS is ignored. This prevents
memory select beeps from occurring when switching MS when MS2 is HIGH.
The part will start in whatever memory the switches are selecting. If a memory is
invalid, the part will default to memory A.
7.13 Audible Memory Change Indicator
Venture can be programmed to produce tones to indicate a memory change. Using
the Interactive Data Sheet Venture can be configured to either enable or disable
the Memory Change Indicator.
When the Memory Change Indicator is enabled, there is an option to have a single
beep for each memory change or multiple beeps.
The amplitude and frequency of the memory change tone can be selected
independent of the Tone Generator settings and can be individually selected for
each memory. When the memory change multiple beep is enabled and the
memory change tone is enabled, then during a memory change operation the
selected tone will beep a code to indicate which memory has been selected. The
beep sequence will be 160ms ON followed by a 160ms OFF time between the
beeps. The memory change beeping code is deciphered in
Table 7-4
.
