MB91490 Series
16
DS07-16912-1E
Order of power turning ON/OFF
Use the following procedure for turning the power on or off. If not using the A/D converter, connect AVCC
= VCC
and AVSS = VSS. Turn on the power supply in the sequence VCC
→ AVCC → AVRH2, and turn off the power in
the reverse sequence.
Source oscillation input when turning on the power
When turning the power on, maintain the clock input until the device is released from the oscillation stabilization
wait state.
Cautions for operation during PLL clock mode
Even if the oscillator comes off or the clock input stops with the PLL clock selected for MB91490 series,
MB91490 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.
Using an external clock
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 k
Ω 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.
C pin
As MB91490 series includes an internal regulator, always connect a bypass capacitor of approximately
4.7
μF to the C pin for use by the regulator.
Software reset on the synchronous mode
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).
