Level trigger
When one of the 12 keys is pressed and held
down, the corresponding group will keep
playing. Once the pressed key is released,
the group will not stop till the included sec-
tions are all completed.
Level hold
When one of the 12 keys is pressed and held
down, the group corresponding to that held
key will play. When the pressed key is re-
leased, the group will immediately stop re-
gardless of the rest.
FLAG
When voices are playing, both FLAG1 and
FLAG2 pins are activated to output one of the
following signals through code option.
FLAG1 can be optioned as one of the following
signal outputs:
None, 3HzB flash, Busy, 6HzB flash, Voice indica-
tor, or End-pulse output
FLAG2, on the other hand, can be set as one of
the following signal outputs:
None, 3Hz flash, 6Hz flash, or Busy output
3Hz/3HzB flash
When voices are playing, the FLAG1 as well
as FLAG2 pins output a 3Hz signal to drive
an LED. The signal is active low, 25% duty.
Once the voice output is terminated, the
FLAG1 and FLAG2 pins become floating out-
puts. When the FLAG1 and the FLAG2 pins
are optioned as 3HzB and 3Hz outputs, they
will be alternately output at a 3Hz rate.
6Hz/6HzB flash
When voices are playing, the FLAG1 pin
outputs a 6Hz signal to drive an LED. The
signal is active low, 25% duty. Once the voice
output is terminated, the FLAG1 pin be-
comes a floating output. When the FLAG1
and the FLAG2 pins are optioned as 6HzB
and 6Hz outputs, they will be alternately
output at a 6Hz rate.
Busy output
When a voice group is playing, the outputs of
both FLAG1 and FLAG2 are turned low, indi-
cating that the chip is busy.
In addition to the above-stated output sig-
nals, FLAG1 can also generate one of the fol-
lowing signals by code option:
