Sound Processor Sound Processor of API4000M use 4 bits ADPCM construction, it has 4 Sound Channel can play music mixed by 4 different type sound.Sample Rate of Sound is during 4KHz ~ 32Khz, each Channel can has different Sample Rate.Each Channel has 2 group Address Register for Sound Data, each group Address Register has a Start Address Register and a End Address Register for Sound Data. Each Sound Channel can be Controlled by Instruction PLAYSP, or Controlled by Melody Processor.Before Play Sound, Address of Sound Data must be set first. The following is the description about setting with Channel, Address, and Sample Rate. 1. Channel : Cn is the no. of Channel in Instruction LDSPADB, LDSPADF, and PLAYSP. Each Channel has A and B 2 group, A and B can’t play together. The folloeing is the Table. Table B.1 Channel CH1 CH2 CH3 CH4 Group A B A B A B A B Cn C1A C1B C2A C2B C3A C3B C4A C4B 5 Ver1.1 INTEGRATED CIRCUITS INC. API4000M SERIES VOICE OTP MODULE 2. Address : Sn is the no. of Sound in Instruction LDSPADB and LDSPADF, which is mean the Start Address and End Address of Memory Sound Data. When Sound is Coding, compiler (API4000SE) will define Address of each Sound, the Address can be used when program is compiling. If you want to set Address of Sound, just choice the no. of Sound. 3. Sample Rate : Data in Instruction PLAYSP is mean Code of Sample Rate, each code is equivalent a Sample Rate. There is 32 type Sample Rate during 4KHz to 32KHz, there is a C.2 Pitch Table in C.Melody Processor. 4. e.g.﹕ LDSPADB C1A , S9 ; LDSPADF C1A , S9 ; PLAYSP C1A , 19 ; LDSPADB C2B , S21 ; LDSPADF C2B , S21 ; PLAYSP C2B , 19 ; LDSPADB C3A , S123 ; LDSPADF C3A , S123 ; PLAYSP C3A , 0 ; LDSPADB C4B , S888 ; LDSPADF C4B , S888 ; PLAYSP C4B , 0 ; /* Set CH1A to Start Address of Sound9 */ /* Set CH1A to End Address of Sound9 */ /* Play Sound9 on CH1, Sample Rate is 16KHz */ /* Set CH2B to Start Address of Sound21 */ /* Set CH2B to End Address of Sound21 */ /* Play Sound21 on CH2,Sample Rate is 16KHz */ /* Set CH3A to Start Address of Sound123 */ /* Set CH3A to End Address of Sound123 */ /* Play Sound123 on CH3, Sample Rate is 4KHz */ /* Set CH4B to Start Address of Sound888 */ /* Set CH4B to End Address of Sound888 */ /* Play Sound888 on CH4, Sample Rate is 4KHz */ C. Melody Processor Melody Processor inside API4000M use Wave Table construction to simulate the tone from musical instrument, It can coinstantaneous play 4 Channel. Each Channel has 2 banks Wave Table, A group is reference Address of treble tone, B group is reference Address of bass tone. treble tone range is during B3(71) ~ B4(83), reference value is B3(71); bass tone range is during E1(40) ~ A#3(70), reference value is A#2(58). Each Melody Note Data is in 2 byte form, 1st byte consists of 5bits Beat Data, 2bits Channel Data, and 1 bit Control Data, 2nd byte consists of 5bits Pitch Data, 1 bit Bank Data, and 2bits Control Data. Melody Processor can processor 32 type Beats, There is a Beat Table on Table C.1. All processible Pitch range is during E1(40) ~ B4(83), total 36 type Note, Table C.2 is a list about Pitch Data, Note, and Sample Rate. Tempo of Melody is set by Function TEMPO Rn, the value of Rn is from Code value of Tempo, Table C.3 is about their reference. Instruction LDMYAD Mn is used to set Start Address of Melody Data in Memory, Mn is the Code of Melody, As Melody compiling, compiler(API4000ME) will define Data Address of each Melody, Data Address can be use in coding. You can use Melody Code to set Address of Melody. Melody’s playing is controlled by Instruction OUT PE, Rn, There is description about how to control in D.Input & Output Data. Melody’s change instrument and end signal is defined in Melody Data, it will active 2 interrupt signal “Change Instrument” and “Song End”, if program detects such signal, it will do correspondent action. 6 Ver1.1 API4000M INTEGRATED CIRCUITS INC.

PROGRAM GUID API4000M is controlled by Program to Play Sound or Play Melody, this chapter will descript how to write a Program. A. Initial State After API4000M Power On, or wake up again after Shut Down, Program Data Address of API4000M is set on Address 000000. You can use instruction OUTPC, OUTPD in the program’s first to set Pin act of PI3 ~ PI0, PIO3 ~ PIO0, and PO3 ~ PO0. Every register in Data Bank after Power On has random initial value, but Shut Down won’t change the value. B. Play Sound Before Playing Sound, Start Address and End Address of Sound Data which would be played must set on the Channel want Play Sound. Use Instruction LDSPADB and LDSPADF set Address of Sound Data. Otherwise, the Channel must be set to Sound Mode by Data Port PE, Sound Processor must be set on, and use Instruction CLINTR to clear residual INTR3 interrupt signal . Then use Instruction PLAYSP to begin playing sound, use INTR3 to detect interrupt signal, and use Instruction INPUT PC to detect the Sound had play over or not. The channel who doesn’t play sound must be set to Melody Mode in Data Port PE, avoid mistake Sound End interrupt signal; exercise Instruction CLINTR, or set Sound Processor to OFF, will clear interrupt signal INTR3. C. Play Melody Before Play Melody, except set Sound Data Address to decide instrument, Address of Melody Data also must be set by Instruction LDMYAD, and set value of Melody Tempo, then use Instruction OUT PE set the channel would play to Melody Mode, set Sound Processor ON, trigger to play Melody. When Melody playing, if the interrupt signal INTR4(Change Instrument) be detected, use Instruction INPUT PB to decision which channel need change instrument, reset trible/bass tone reference Sound Data Address of the channel directly. Melody play over will send a interrupt signal INTR2(Song End), If you want pause or stop play Melody play, use Instruction OUT PE to set Melody to OFF. 10 Ver1.1 INTEGRATED CIRCUITS INC. API4000M SERIES VOICE OTP MODULE D. External Interface PI3 ~ PI0 , PIO3 ~ PIO0 , and PO3 ~ PO0 is the link for API4000M connecting with outside, Instruction INPUT PA, OUT PA, or OUT PB, can input or output Data. PI3 , or PI2 ~ PI0 that set to Input Pin, or PIO3 ~ PIO0 of Input Pin set with Trigger has any pin is High Level, there will send a interrupt signal INTR1(Key In), and Wake Up API4000M in Shut Down.
