전화기 다이얼신호의 기능선택 방법How to select the function of the telephone dial signal

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 본 발명의 CPU을 이용한 전화기 다이얼 신호기능 선택 블럭도, 제4도는 본 발명에 따른 플로우 챠트도.3 is a block diagram of a telephone dial signal function selection using a CPU of the present invention, and FIG. 4 is a flowchart of the present invention.

Claims (2)

정상적으로 CPU(100)의 키주사 출력포트(P0~P2)에서 키 주사를 할때는 기능제어포트(P3)를 하이 상태로 유지하여 키 주사에 지장을 주지 않게하는 단계와, CPU(100)의 키 주사 출력포트(P0~P3)에서 키 주사를 하지않을때는 기능 제어포트(P3)를 로우 상태로 세팅하여 스위치(SW1~SW4)에 따라 키 입력포트(K0~K3)의 기능 선택 데이타 값을 결정하는 단계를 포함하여 구성되는 것을 특징으로 하는 전화기 다이얼 신호의 기능 선택 방법.When performing key scan at the key scan output ports P0 to P2 of the CPU 100 normally, the function control port P3 is kept high so as not to interfere with the key scan, and the key scan of the CPU 100. When no key scan is performed at the output ports P0 to P3, the function control port P3 is set to the low state to determine the function selection data value of the key input ports K0 to K3 according to the switches SW1 to SW4. A method of selecting a function of a telephone dial signal, characterized in that it comprises a step. 제1항에 있어서, 키 입력포트(K0~K3)가 하이일때 개폐비(M/B Ratio)의 스위치(SW1)가 쇼트이면 1:2이고 오픈이면 2:3이며 다이얼속도(SPD)의 스위치(SW2)가 쇼트이면 10pps이고 오픈이면 20pps이며 톤/펄스(T/P)의 스위치(SW3)가 쇼트이면 펄스이고 오픈너이면 톤이며 스위치(SW4)가 쇼트/오픈이면 옵션널이 되는 단계를 포함하여 구성된 것을 특징으로 하는 전화기 다이얼신호의 기능선택 방법.The switch of the dial speed SPD according to claim 1, wherein when the key input ports K0 to K3 are high, the switch SW1 of the M / B ratio is 1: 2 when the short is open and 2: 3 when the switch is open. If (SW2) is short, it is 10pps, if it is open, it is 20pps, and if the switch (SW3) of tone / pulse (T / P) is short, it is pulse, if it is opener, it is tone; if the switch (SW4) is short / open, it becomes optional. Method for selecting a function of the telephone dial signal, characterized in that configured to include. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
