• Example of Using an External Clock
Use the following procedure for turning the power on or off. If not using the A/D converter, connect AV
and AV
the reverse sequence.
When turning the power on, maintain the clock input until the device is released from the oscillation stabilization
wait state.
Even if the oscillator comes off or the clock input stops with the PLL clock selected for MB91470/480 series,
MB91470/480 series may continue to operate at the free-run frequency of the PLL’s internal self-oscillating
oscillator circuit.
Performance of this operation, however, cannot be guaranteed.
When using an external clock, you must always input clock signals with opposite phase from X0 pin to X1 pin
simultaneously. However, as the X1 pin halts with an output at the "H" level during stop mode, insert a resistor
of approximately 1 kΩ externally to prevent a conflict between the two outputs if using stop mode (oscillation
stop mode).
The figure below shows an example of how to use an external clock.
As MB91470/480 series includes an internal regulator, always connect a bypass capacitor of approximately
4.7 µF to the C pin for use by the regulator.
Be sure to meet the following two conditions before setting 0 to the SRST bit of STCR (standby control register)
when the software reset is used on the synchronous mode.
• Set the interrupt enable flag (I-Flag) to interrupts disabled (I-Flag=0).
• Not used NMI
