Claims (2)

추가형 컴팩트디스크 플레이어의 서브코드 기록방법에 있어서, 기록명령시 인터럽트 마스크 온하고 기록 준비완료 상태를 변조부에 알리는 제1과정과, 상기 제1과정 수행후 TOC데이타를 기록하고 서브코드 시작점을 세트하고 프레임 인덱스를 크리어하며 블럭카운터 및 트랙번호를 세트하여 초기화하는 제2과정과, 상기 제2과정수행후 소정 주기를 갖는 인터럽트를 인에이블하고 시간을 세트하는 제2과정과, 상기 제3과정 수행후 CLV제어 후 타임인터럽트 수행결과가 1블럭임시 블럭카운터를 증가한 후 음악의 끝으로 판명되면 트랙번호를 증가시키고 서브코드를 변경하는 제4과정과, 상기 제4과정 수행후 기록 완료 여부를 체크하여 기록완료시 초기화 작업후 타임 인터럽트를 해제하고 시스템 인터럽트를 인에이블 시킨후 종료하는 제5과정으로 이루어짐을 특징으로 하는 방법.A subcode recording method of an additional compact disc player, comprising: a first process of interrupt mask on at the time of a recording command and informing the modulator of a readiness completion state; recording TOC data after performing the first process and setting a subcode start point; A second process of clearing a frame index, setting a block counter and a track number, and initializing the frame index; and enabling an interrupt having a predetermined period after performing the second process and setting a time; and performing the third process. After the CLV control, if the result of the time interrupt is 1 block, the block counter is increased, and if it turns out to be the end of the music, the fourth step of increasing the track number and changing the sub code is performed. When writing is completed, after the initialization operation, release the time interrupt, enable the system interrupt, and then terminate the process. Method of claim. 제1항에 있어서, 타임인터럽트가 인터럽트 타임을 다시 세트하고 버퍼에 기록할 데이타를 어큐물레이터로 옮기는 제1단계와, 버퍼에 상기 데이타를 기록하고 서브코드를 다음 바 블럭데이타로 수정하는 제2단계와, 상기 제2단계 수행후 서브코드 테이블 억세스를 위한 인덱스를 증가시키고 종료하는 제3단계로 이루어짐을 특징으로 하는 방법.2. The method of claim 1, wherein the time interrupt sets the interrupt time again and moves data to be written to the buffer to the accumulator, and the second writes the data to the buffer and modifies the subcode to the next bar block data. And a third step of incrementing and terminating the index for accessing the subcode table after performing the second step. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
