13.1.4 Time supplying “L” level to RESET pin
Time supplying “L” level to the RESET pin varies according to the state of the clock oscillation circuit.
When the oscillator is stably oscillating or a stable clock is input from the X
If the oscillator is not stably oscillating (including a power-on reset and In Stop mode), supply “L” level
2 µ s or more.
until the oscillation is stabilized.
The time to stabilize oscillation varies according to the oscillator. For details, contact the oscillator
manufacturer.
Figure 13.1.8 shows the power-on reset condition. Figure 13.1.9 shows an example of a power-on reset
circuit.
For details about Stop mode, refer to “Chapter 10. STOP MODE.” For details about clocks, refer to
“Chapter 14. CLOCK GENERATING CIRCUIT.”
