predefined modes are described as below:

o Single Mode

Enter Single Mode after n-SPK is turned on.

o Back To Last Mode

After n-SPK is turned on, it enters into the last mode which n-SPK stayed before powering off. For example, if

n-SPK is in the Single Mode before it is powered off, it will enter into Single Mode in next powering on.

o Intelligent Twin Pairing

When n-SPK is powered on, it enters Twin Mode Pairing and tries to discover a matched n-SPK to create a

connection upon the presetting group code. The roles of Twin Master and Twin Slave are determined by

automatic negotiation between the two matched n-SPKs.

o Factory Paired

Two n-SPKs are pre-paired and assigned the roles of Twin Master and Twin Slave in production. These two n-

SPKs will try to establish the connection after they are powered on.

o Switch Control

There are two pins which are P2_4 and P3_0 determine the behavior of n-SPK. The corresponding roles of

these two pins are mutually exclusive and could be configured to be Twin Master or Twin Slave. That is, if

P3_0 is set to Twin Master, P2_4 must be Twin Slave. Base on above configuration, If P3_0 is pulled to high

supports two pre-defined Special Keys in n-SPK.

3.12.3 Function Mapping Table

The Function Mapping Table is to set the functions for the triggered events in all states that divided by call status.

There are three kinds of button events in the Function Mapping Table; Short Press, Long Press and Special Key. If

a function is set to certain button event, it means the function will be performed when this button event is

triggered. For example, if the function Forward is set to the Short Press event of Button4 in Standby (No talk)

state, when users short press Button4, the music will forward to next track. More information about performed

functions and call states will be described later.

3.12.4 Combined Function Table

The Combined Function Table is an expanded function of button settings and divided into two classes which are

classified according to profile links states and according to music streaming states. There are four kinds of button

functions are called Combine Function0, Combine Function1, Combine Function2 and Combine Function3(See

3.12.6 Button Functions). These four button functions can be set in normal key operation and special key

operation and are triggered in the Function Mapping Table. If one of them is triggered, the corresponding button

events will be triggered by profile links states and music streaming state. Under the profiles links state, these

states are called No Link, Only A2DP, Only Mono and Two Links; under the music streaming state, they are called

AV Idle and AV Play. If Combine Function0 and Combine Function1 are set and clicked to perform, the

corresponding actions will be took and based on profiles links states; if Combine Function2 and Combine

Function3 are set and clicked to perform, the corresponding actions will be took and based on music streaming

states. For example, if the Combine Function0 is set to the Short Press event of Button4 under Standby (No talk)

state in the Function Mapping Table and the Play/Pause is set in Combine Func0 at Two Links in the Combine

Function Table, users press Button4 shortly under Standby(No talk) state, the player will start to play or pause

General: Use Group Access Code. We define that Group Access Code is a company code or a product code. When users want to design-in with this chip, they have to submit requirement for their unique company code and product code. Under this method, Twin Master and Twin Slave are needed to configure the same Group Access Code and they are discovered and paired with each other which have the same code. When Twin Master discovered and tried to pair with Twin Slave, Twin Master discover and pair with Twin Slave which has the same code. If there are many Twin Masters and Twin Slaves under twin mode pairing mode at the same time, we can’t expect one of Twin Masters will pair with the specific Twin Slave.

Dedicate: Use Dedicate Twin Speaker Pairing Access Code. When selecting this method, Twin Master and Twin Slave must be a paired on manufacturing. Base on Dedicated Twin Speaker Pairing Access Code, Twin Master tries to pair with the specific Twin Slave which has the same code.

Recovery: Use the access code of Twin Master. This access code is determined by Bluetooth address of Twin Master. Twin Master first uses Group Access Code to discover and pair with Twin Slave. Both of them record the access code of Twin Master. Next time, Twin Master and Twin Slave are a paired and will use the recording access code to do the twin mode paired.
