7. 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.
