13.5.3. Attention of FOUT function.
Note 1
Valid voltage range for FOUT function is 1.6V to 5.5V. (Please see operating voltage.)
Note 2
A disappearance of the FOUT output when the voltage sharply went up and down.
For example, Vcc voltage of the RTC is come and go between Main power and backup battery.
The clock output from FOUT disappears then during several miliseconds when a sharp voltage change happens.
Please check that there is not a problem by this characteristic on your system.
An reference example of a power up and down timing without affect to FOUT.
Valid Vcc voltage range
for using FOUT.
tFFOUT
Please make speed to descend of a power supply voltage loose than 4ms/V.
tRFOUT
Please make speed to rise of a power supply voltage loose than one ms/V.
5.5V
1.6 V
tFFOUT
tRFOUT
Note 3
The effect of STOP bit to FOUT functions.
When STOP = "1", 32768Hz and 1024Hz output is possible.
But 1Hz output is disabled.
