APPLICATION
2.8 Clock generating circuit
2.8.2 Clock generating circuit application examples
(1)
Status transition during power failure
Outline: The clock is counted up every one second by using the timer interrupt during a power
failure.
Fig. 2.8.2 Connection diagram
Specifications: •Reducing power dissipation as low as possible while maintaining clock function
•Clock: f(XIN) = 8 MHz, f(XCIN) = 32.768 kHz
•Port processing
Input port: Fixed to “H” or “L” level on the external
Output port: Fixed to output level that does not cause current flow to the external
(Example) When a circuit turns on LED at “L” output level, fix the
output level to “H”.
I/O port: Input port
→ Fixed to “H” or “L” level on the external
Output port
→ Output of data that does not consume current
VREF: Stop to supply to reference voltage input pin by external circuit

Power failure detection signal
Input port
(Note)
Note: Signal is detected by inputting to each input port,
interrupt input pin, and analog input pin.
