Frame Frequency
HT1670 provides three kinds of frame frequency option by command code; 64Hz, 89Hz and 170Hz respectively. FRAME
64Hz provides 64Hz frame frequency. FRAME 89Hz provides 89Hz frame frequency. FRAME 170Hz provides 170Hz
frame frequency.

WDT
The time base generator and WDT share the samecounterwhichisdividedby256.TheIRQclockcanbeprogrammedas
1Hz, 2Hz, ...., 128Hz output. TIMER DIS/EN/CLR, WDT DIS/EN/CLR and IRQ EN/DIS are independent from each other.
Once the WDTtime-out occurs, the IRQ pin will remain at a logic low level until the CLR WDTor the IRQ DIS command
is issued.
If an external clock is selected as the system frequency source, the SYS DIS command turns out invalid and the power
down mode fails to be carried out until the external clock source is removed.
