6.1.1
• Low-speed clock: 32.768 kHz crystal oscillation mode
• High-speed clock: Software selection
6.1.2
The clock generation circuit generates and provides a low-speed clock (LSCLK), 2× low-speed clock (LSCLK2), a
high-speed clock (HSCLK), a system clock (SYSCLK), and a high-speed output clock (OUTCLK).
LSCLK×2, and HSCLK are time base clocks for the peripheral circuits, SYSCLK is a basic operation clock of CPU,
and OUTCLK is a clock that is output from a port.
For the OUTCLK output port, see Chapter 18, “Port 2”.
Additionally, for the STOP mode described in this chapter, see Chapter 4, “MCU Control Function”, and for BLD, see
Chapter 25, “Battery Level Detection Circuit”.
Figure 6-1 shows the configuration of the clock generation circuit.
Note:
This LSI starts operation with a clock generated by dividing the 500 kHz RC oscillation frequency by 8 after power-on
or a system reset. At initialization by software, set the FCON0 or FCON1 register to switch the clock to a required
one. Operation of this LSI is not guaranteed under a condition where a low-speed clock is not supplied.
− Capable of generating LSCLK × 2 (64 kHz) to be used for some peripherals.
− 500 kHz RC oscillation mode
− Crytal/ceramic oscillation mode
− Built-in PLL oscillation mode
− External clock input mode
− 2 MHz RC oscillation mode
