KEY6 as a stop key (by mask option)
When KEY6 functions as a stop key, any voice output
can be stopped by pressing KEY6.
KEY2~KEY6 as a repeat key
As a repeat key, the sections included can be played
sequentially and repeatedly until other key input is
triggered.
Key Features
Key priority
When six keys are triggered simultaneously, the out-
put voice is determined by the key priority as shown
below:
KEY1>KEY2>KEY3>KEY4>KEY5>KEY6
Key debounce time
There are three kinds of key-in debounce time to be
selected by mask option, namely, 1.2ms, 22ms,
45ms. The key debounce time varies with the value of
the system frequency.
Pull-high resistance
Four kinds of key input pin pull-high resistance can
be selected by mask option, namely, 0k , 50k ,
100k
VDD, temperatures and the chip itself due to pro-
cess variations.
and 200k . The resistance may vary with
Trigger mode
The two keys can optioned as one-shot trigger mode
or normal mode.
One shot
When one of the six keys (KEY1~ KEY6) is pressed
momentarily or held down, the group corresponding
to that key will play once.
Normal trigger
When one of the two keys is pressed and held
down, the corresponding group will continue play-
ing. Once the pressed key is released, the group
will not stop until the included sections are all com-
pleted.
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:
OFF, 3HzB flash, Busy, 6HzB flash, 3hz, 6Hz or End-pulse
output
FLAG2, on the other hand, can be set as one of the fol-
lowing signal outputs:
OFF, 3Hz flash, 6Hz flash, or Busy output.
3Hz/3HzB flash
When voices are playing, FLAG1 as well as FLAG2
pin outputs a 3Hz signal to drive a LED. The signal is
active low, 25% duty. Once the voice output is termi-
nated, the FLAG1 and FLAG2 pins become floating
outputs. When the FLAG1 and the FLAG2 pins are
optioned as 3HzB and 3Hz output, they will alternately
output at a 3Hz rate.
