EMFeSL XC Board Users Handbook 1

1 Overview

The EMFeSL XC (EMF or Evaluation Module Flash) Board supports

eSL/eSLS/eAM/eAMS series DSP devices. It conveniently facilitates

downloading of your program and audio data into its flash memory (SPI &

DROM) for instant verification and debugging of the data. You can download

directly to the EMF Board through printer port or indirectly via the ICE Board

(option). The later connects to the host through USB which offers faster

downloading of programs.

The EMF Board connects to the ICE Board through a 10-pin JTAG cable. It can

also be directly connected and operated on-line with host PC through printer

port as well as function stand-alone to independently playback pre-downloaded

SPI program and audio data with power and speaker connected to it.

3.1.1 System Installation and Power-up

1) Connect EMF Board to ICE Board via JTAG cable.

2) Connect USB cable between ICE Board and host.

3) Plug power adapter to ICE Board.

WARNING!!

Use power adapter included with the ICE Board package only.

4) Connect an 8 speaker (user provided) BJT SPEAKER (P5)OR OP

SPEAKER (P4) connector on EMF Board.

5) Turn on the ICE Board power switch (you will be prompt to upgrade your

USB driver).

6) Upgrade your USB driver with the USBDriver provided in the eSL IDE

package.

7) Run the eSL IDE program (refer to the separate eSL Series IDE Users

Guide).

3.2 Stand-Alone (Boot) Mode

Stand-Alone or Boot Mode allows the EMF Board to independently playback

pre-downloaded SPI program and audio data without linking to ICE Board orhost. This mode converts the EMF Board into a very convenient portable demo

device. All it needs is a battery and a speaker as illustrated in Figure 3-2 below.

3.2.1 System Installation and Power-up

1) Connect an 8 speaker (user provided) to BJT SPEAKER (P5)OR OP

SPEAKER (P4) connector on EMF Board.

2) Connect a 3V battery pack (user provided) to the EMF Board power

connector.

4 Hardware Overview

4.1 Board Connectors

The major components of the EMFeSL XC Board are:

1. eSLZ000 device

2. JTAG Connector (J10).

3. Two LED that indicate eSL/eSLS/eAM/eAMS series CPU mode (D2, D3).

4. BJT (TR1), RB Connector, Speaker for BJT (P5) and OP(P4) function.

5. Microphone Connector(J9), Touch panel Connector (J11)

6. Battery 4.5V or 3V DC IN (BAT1). Be sure to ascertain the BAT1 positive

and negative terminals.

4.2.1 Microphone Output Mode Option (JP10)

The microphone offers two types of output, i.e., AMPO Simple Analog Output

(default) and AMPO Digital Output (through PORTC5 A/D input pin). JP10 is

used to set the desired AMPO output as illustrated below:

A.1 Sleep Mode Current Consumption for Kerneland IO

1. Connect EMF Board to ICE Board via JTAG cable.

2. Download SPI Boot program to EMF Board via ICE Board.

3. In accordance with chapter 3.2 Stand-Alone (Boot) Mode Hardware setup.Connect Current meter and Power supply(3v/4.5v) as illustrated below.

4. Short the Reset about 1 second, program will run code from POWERON

label and finally run into sleep mode loop, then user should make sure thatprogram go into sleep mode. You can watch that LED2 and LED3 whether

that LED go out or not.

5. Watch the Current meter, the current meter value is just kernel and IOoperation current.
