Figure 6-2 shows the configuration of the low-speed clock generation circuit.
A low-speed clock generation circuit is provided with an external 32.768 kHz crystal. To match the oscillation
frequency by using a trimmer capacitor, connect external capacitors (C
In STOP mode, V
Impedance state).
When the ENMLT bit of FCON1 is set to “1”, the 2× low-speed clock circuit starts to generate the LSCLK×2(64kHz)
Notes:
− Install a crystal as close to the LSI as possible and make sure that signals causing noise and power supply wiring are
− Note that oscillation may stop due to condensation.
