Retriggerable TG

Retriggerable

TGm

means

the

sentence

addressed by TGm could be retriggerred by other

TGs.

See Timing diagrams I & III. Of course, it can be

retriggered by itself. See Timing diagrams I.

Ramp up

When a sentence starts playing from silence, the

audio output (either Cout or V1, V2) starts from

zero current and ramps up to the half scale of full

audio output in 128 steps. These 128 steps' gaps

are uniform. After these 128 steps accomplished

the sentence sound data begins.

As this is hardware implement, the first data byte

of a sound file is asked to be center value. for 8 bit

PCM data file, the center value is 80h.

Herein zero output does not mean zero potential,

neither ground.

Ramp down

Whenever a sentence is played and finished, the

audio outputs (either Cout or V1, V2) try going

from last data down to zero.

There

is an interval provided in width t PL.

Without redundant ramp down and up within this

interval, the audio output keeps at center value of

full audio signal. This is to keep the audio output

sounds continued if there comes a latter sentence.

This interval starts from the last data pixel to the

ramp down starts.

Because the output is kept at center value of full

audio signal, the last data pixel of a sound file is

recommended as center value.

For 8 bit PCM

data file, the center value is 80h.

After this t PL interval finished and there comes no

new comer sentence, the audio output gradually

reduces in 128 steps from the center value of full

audio signal down to zero output.

Herein zero output does not mean zero potential,

neither ground.

Trigger

A trigger mentioned in this data sheet does mean

either a certain pin or an activated input signal. It

could be:

(1) a high signal to straight input

(2) a low signal to straight input

(3) a cross touch of a pin K and a pin RW.

Power on play

This

function

is

not

provided

even

have

appropriate wiring.

Active high and active low

An input pin can be masked as either active high

or active low.

Terms

This active-high pin is internal pull low and no latch.

This active-low pin is internal pull high and no latch.

Small Loop & Large Loop

This is a function belongs to OKY.

OKY plays

many sentences, up to 32.

User can play 1st

sentence through 32nd sentence if user selects

"large loop". At this time the sentence lst, 2nd, 3rd

and 4th may be triggerred by TGs.

User will play 16 sentences, from 17th through

32nd sentence, when user selects "small loop".

User may have less sentences triggered by OKY at

this selection. But user definitely can prevent those

OKY's sentences triggerred by TGs.

Cycle Loop

This is a count number ranges 1 through 32 which

defines the sentence range OKY will play. This

number is user definable and could be equal to or

less than sentence defined.

Continuous OKY & Home OKY

This is a function belongs to OKY and determines

the play sequence when the first OKY comes after

any other trigger addressing.

The "continuous"

preserves the sequence while the "home"rewinds

to the very beginning. This very beginning means

either 17th sentence or 1st sentence which is

determined by Loop Size - small or large.

You will see a term S.W.A.I. in this data sheet, it

means sequence when after interrupt by other

trigger addressing.

Ramdom Play OKY

A trigger at OKY will play a sentence randomly out

from specified sentence group.

But not every mask option combination provides

random play. It is provided only when masked as

edge and unhold. It is regardless retrigger or not.

Herein sentence group is determined by cycle loop

and small / large loop.
