8bit도 해봐야 하는데.. 회로 구성이 일단 4bit로 되어있으니
4비트 강제 설정을 해주어야 하는데
문서의 실수인지 Function Set이 12 비트이다..
그냥 무시하고 8바이트로 보내도 문제는 없는 것 같긴하다.

There is one file for each user's crontab under the /var/spool/cron/crontabs directory. Users are not
allowed to edit the files under that directory directly to ensure that only users allowed by the system to
run periodic tasks can add them, and only syntactically correct crontabs will be written there. This is
enforced by having the directory writable only by the crontab group and configuring crontab command with the
setgid bid set for that specific group.

그래서! 외부 16MHz 크리스탈로 바꾸려고 했는데!! 망했어요!!! ㅠㅠ
아무생각없이 외부 클럭이니까.. Ext. Clock 이면 될꺼야. 클릭.. 어.. 안읽히네?!?!?
흑흑 Atmega8의 TQFP 패키지는 이렇게 생겨 먹었고.. XTAL1에 클럭을 넣어줘야 하니..
저 핀에 점퍼를 날려서 하면 참.. 쉽죠? 가 될 거 같을.... 리가 있나!!! ㅠㅠ 망했어요!!!! ㅠㅠ
