6.3.2.2
In crystal/ceramic oscillation mode, both the P10/OSC0 pin and the P11/OSC1 pin are used for crystal ceramic
oscillation.
In crystal/ceramic oscillation mode, a crystal or a ceramic resonator is externally connected to the P10/OSC0 and
P11/OSC1 pins. If the high-speed oscillation clock pulse count reaches 4096 after oscillation enable, the clock is output
to OSCLK (high-speed oscillation clock).
Figure 6-5 shows the circuit configuration in crystal/ceramic oscillation mode.
Notes:
− The crystal/ceramic oscillation mode can be used within a V
− Install a crystal or a ceramic resonator as close to the LSI as possible and make sure that signals causing noise and
− Note that oscillation may stop due to condensation.
− The crystal or the ceramic resonator connected to the P10/OSC0 and P11/OSC1 pins should not exceed the
according to the operating voltage range by using the power supply voltage detection circuit (BLD). See Chapter
25, “Battery Level Detection Circuit” for details of BLD.
power supply wiring are not near the crystal or the ceramic resonator and their wiring.
