Abstract

본 발명은 마이크로 제어장치의 유사한 주변 칩 세트의 변화에 따른 공용화 장치 및 방법에 관한 것으로, 일반적으로 주변 칩의 버젼을 높이거나 롬 마스킹의 경우엔, 그에 따른 소프트웨어를 따로 작성한 후 롬에 써 넣어야만 일치시킬 수 있는 문제점이 있으므로, 본 발명은 이러한 문제점을 해결하기 위해 마이크로 제어장치 내부의 프로그램을 그대로 두고 각각의 칩에 해당하는 프로그램을 동작시켜 마이크로 제어장치를 다시 프로그램 할 필요가 없으며, 다른 주변 칩들이 바뀌어도 자동적으로 보호해 줄 수 있다.The present invention relates to a device and method for sharing a peripheral chip set of a microcontroller according to a change in a peripheral chip set. Generally, in case of increasing the version of a peripheral chip or ROM masking, software corresponding thereto must be written separately and written in ROM In order to solve such a problem, the present invention eliminates the need to re-program the microcontroller by operating a program corresponding to each chip while leaving the program in the microcontroller as it is, Can be automatically protected even if they change.

Claims

A method of sharing a microcontroller, comprising: a first step (S1) of setting a port so that peripheral chips can be determined; A second step (S2) of checking input data and input signals coming from the peripheral chips through the input port; A third step S3 of determining whether the input is a low reset or a high reset; A fourth step (S4) of determining whether a low reset or a high reset is a low reset after determining the third step (S3); A fifth step (S5) of performing a service program for the low reset chip if the reset is performed after the fourth step (S4); A fifth step (S5) of performing a service program for a high reset if it is not a low reset after the fourth step (S4); A seventh step (S7) of performing a service program for a characteristic unique to a peripheral chip if it is neither a low nor a high reset after the third step (S3); (S8) of performing a common program after the fifth step (S5), the sixth step (S6), the seventh step (S7), and the like of the microcontroller A common method according to.
