Section 4 Clock Pulse Generators
4.5.2
When using a crystal resonator (ceramic resonator), place the resonator and its load capacitors as
close as possible to the OSC1 and OSC2 pins. Other signal lines should be routed away from the
resonator circuit to prevent induction from interfering with correct oscillation (see figure 4.11).
Note: When a crystal resonator or ceramic resonator is connected, consult with the crystal
4.5.3
Figure 4.12 shows the oscillation waveform (OSC2), system clock (φ), and microcomputer
operating mode when a transition is made from standby mode, watch mode, or subactive mode, to
active (high-speed/medium-speed) mode, with an resonator connected to the system clock
oscillator.
As shown in figure 4.12, when a transition is made to active (high-speed/medium-speed) mode,
from standby mode, watch mode, or subactive mode, in which the system clock oscillator is
halted, the sum of the following two times (oscillation start time and wait time) is required.
(1)
The time from the point at which the system clock oscillator oscillation waveform starts to change
when an interrupt is generated, until the system clock starts to be generated.
