=BOD - (brownout detect) - 일정전압 이하 리셋 = > 일정전압 이상 동작되도록 ( 안정적 동작)

=레지스터

=회로도

- 레귤레이터(규칙적인) - 공급되는 전압이 변하더라도 일정한 전압 공급

-승압 X :

-나머지는 열로

=전보 -------- 릴레이(원래신호 원복) ------도착

1 - 3.3V

0 - 0V

MAX3232 - 처리 칩

RS232(편차 24V)

1 - (+12V)

0 - (-12V)

-P20 - 기준 ADDR

-P1248 - OFFSET(차감/상쇄/벌충 하다)

-폰노이만 (한 영역에 다 있음)

=LED ON/OFF
