Functional Description
Display Memory Structure static display organized into bits stores display data. contents directly mapped contents driver. Data beaccessed theREAD,WRITEand READ-MODIFY-WRITE commands. following mapping from patterns. Time Base Watchdog Timer time base generator share same divided (/256) counter. TIMER DIS/EN/CLR, DIS/EN/CLR EN/DIS independent from each other. Once time-out occurs, will stay logic level until command issued.
