Preliminary
KEY2 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 two keys are triggered simultaneously,
the output voice is determined by the key pri-
ority as shown below:
KEY1>KEY2
Key debounce time
Therearethreekindsofkey-indebouncetimeto
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 resis-
tance can be selected by mask option,
namely, 0k , 50k , 100k
resistance may vary with VDD, tempera-
tures and the chip itself due to process vari-
ations.
and 200k . The
Trigger mode
The two keys can optioned as one-shot trigger
mode or normal mode.
One shot
When one of the two keys (KEY1, KEY2) 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 playing. Once the pressed key is
released, the group will not stop until the
included sections are all completed.
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 following 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 terminated, 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.
