Functional Description
Display Memory Structure static display organized into bits stores display data. contents directly mapped contents driver. Data accessed READ, WRITE 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 remain logic level until command issued. external clock selected source system frequency, command turns invalid power down mode fails carried until external clock source removed. Buzzer Tone Output simple tone generator implemented HT1626. tone generator output pair differential driving signals which used generate single tone. Command Format HT1626 configured software setting. There mode commands configure HT1626 resource transfer display data.
