System Control Instruction Format Code Cycle Bytes Instruction Description CLINTR ﹔ C8 1 1 Clear Interrupt Signal INTRE ﹔ C9 1 1 Make system can receive interrupt signal. SHUTDN ﹔ CA 1 1 System shutdown. PS : (1). Before executiving SHUTDN Instruction, be sure to executive INTRE Instruction first to assure system can be restarted after shutdown. B. 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 |
