LEDX is turned off for t ONL and then turns on for 2 x t

ONL. And cycles. The LEDY turns off right after LEDX

turns on.

LEDY is turned off for t ONL and then turns on for 2 x t

ONL. And cycles.

This 340 ms t ONL equals 1 over 2.93. Of course, this

is valid within sound activated period.

This t ONL is sample rate dependent.

If user needs 4 LED lamps to perform ring flash.

These 4 pins are only candidates.

Other 4 - lamps combinations are not guaranteed.

Ring Flash 5 LEDs slow & inverse

User can specify 5 LEDs ring at slow & inverse.

It means

LEDS is turned off for t ONL and then turns on for 4 x t

ONL.

And cycles.

The LEDW turns off right after

LEDS turns on.

LEDW is turned off for t ONL and then turns on for 4 x t

ONL.

And cycles.

The LEDX turns off right after

LEDW turns on.

LEDX is turned off for t ONL and then turns on for 4 x t

ONL. And cycles. The LEDY turns off right after LEDX

turns on.

LEDY is turned off for t ONL and then turns on for 4 x t

ONL. And cycles. The LEDZ turns off right after LEDY

turns on.

LEDZ is turned off for t ONL and then turns on for 4 x t

ONL. And cycles.

This t ONL is sample rate dependent.

Initial high & Initial low

This is a function belongs to OUTs. It defines the state

only from power on to the first audio activated. It is

effective for all 15 features.

"Initial low" means user want this OUT pin is put to low

whenever this chip is power on. "Initial high" means

vice versa.

Initial high is good for LED because that high will forbid

the LED to be turned on, user want not keep the LED

light even user don't use very long time since user

power on the chip.

So, we suggest user to define

"initial high" whenever LED is chosen for that OUT pin.

But it is not absolutely right. User may on purpose turn

it on once user likes it.

Initial low is good for Busy because that low will have

every Busy starts from zero on whole time line. So,

user are suggested to define "initial low" whenever

Busy is chosen for that OUT pin.

But it is not absolutely right. User may on purpose

have a high to do whatever user want, to turn a motor

running this way or tell a situation since power on, etc.

The similar situation for DC high or low. The similar

situation for Stop signal.

DC 0 & DC 1

DC 0 is read as D.C. zero and is quick form of DC low.

DC 1 is read as D.C. one and is quick form of DC high.

This is a function belongs to OUTs. User may be

confused it with Busy. It is similar to Busy signal but it is

not only valid during audio is being played, like Busy, but

also valid after the audio has been played. Its response

lasts until next audio entry is activated.

DC0 means zero potential (Vss) while the DC1 means

the Vdd.

Output pins at Cout plays mute

Mute has two types in MVI's Snn07 voice chip. Both

these two types of mute are treat as sound for

considering the output.

The Stop is generated after

every mute. Busy is valid during every mute.

LED works at every mute.

Be careful that t PL interval does not count in mute.

Stop Pulse

Stop pulse is genrated right at the sound ends and lasts

for 40 ms typically. The mask options provide either high

stop pulse or low stop pulse.

Stop pulse width is

determined on the sample rate as well as the pitch of

that playing entry when stop pulse occurs.

This 40 ms stop pulse is sufficiently wide to activate TGA

(or TGB or TGC) by feed back wiring.

Sample Rate

There are some parameters depend on sample rate.

They are debounce time, ramp up time, ramp down time,

plain time, LED Ring frequency, LED fix flash frequency

and Stop pulse width. The numbers mentioned in this

data sheet are based on 6 KHz sample rate if not

specified. Higher SR has LED flashes quicker. Higher

SR makes Stop pulse shorter.

Higher SR let the

debounce time shorter. Higher SR makes the ramp up

time quicker. Higher SR makes the ramp down time

quicker, too. Higher SR makes shorter plain time.

This chip provides multi-SR function. What it means is

that user can digitize two different sounds in different SR

but plays them by a common Rosc. For example, user

has rocket sound digitized in 9.5 KHz but have rooster

digitized at 6 KHz. While manufactured, user just specify

different pitch numbers on request form - 4 for rocket and

1 for rooster.

The chip could be played those two

sounds at a Rosc fit for 6 KHz SR. Because that "pitch

4" at 6 KHz Rosc means 6 KHz playback while "pitch 1"

at 6 KHz Rosc meas playback in 1.6 times 6 KHz.

The 600K ohm Rosc playback 6 KHz sample rate

typically, but just typical.

Smaller Rosc playbacks

quicker - Higher pixel rate. MVI provides voice chip with

very flat response for playback vs working voltage.

Higher working voltage get slower playback but

insignificantly.

Lower Key Priority

What's the result when multi triggers are activated simul-

taneously? Which trigger is acknowledged among these

ninteen? Among these sixteen? Among these three?

Between these two?
