DBMFL-ENG2 DBMFL-ENG2, support 5 function mode by PB0~PB3, PD0~PD2 and Dip switch 5 modes are : Key trigger mode, Sequential trigger mode, CPU parallel mode, CPU serial mode and MP3 mode. ( see mode details in spec ) DBMFL-ENG2-DIP Demo Board is for programming aMTPxxM, 28PIN DIP DBMFL-ENG2-SOP Demo Board is for programming aMTPxxM, 28PIN SOP Connect DBMFL-ENG2 to APLUS WRITER ( part no : aSPI28W ) to program as below DBMFL-ENG2-DIP aSPI28W Writer DBMFL-ENG2-SOP aSPI28W Writer After program finished, remove cable. Then connect battery and speaker to DBMFL-ENG2 to listen. Warning: aSPI28W PWR pin will offer power to circuit. So before connecting to aSPI28W, you must remove any other power source Ver 1.1 2/5 1/6/2012 Integrated Circuits Inc. DBMFL-ENG2 DBMFL-ENG2 manual： 3. 1. 2. 4. 6. 7. 1. 2. 3. 4. 5. 6. 7. Working Voltage ： 3V Function Switch ： PB0 to PB3 and PD0 to PD2 and DIP switch. Output Option ： Set aP4890 (DAC) or PWM Speaker connect ： Connect Speaker to 4890 (DAC) or PWM Reset Key ： Reset aMTPxxM Program Pin ： Connect aSPI28W to Program Volume Control ： DAC volume control 5. 1. 3. 2. 4. 6. 7. 5. Note：Dac or PWM speaker output should be same as DAT setting. If compiler DAT by PWM, then speaker need to connect PWM. If by DAC, then speaker should connect to DAC.
