2.2 System Clock Controller
2.2.1 Clock Generator
The system clock controller consists of a clock generator, a timing generator, and a standby controller.

and peripheral hardware. It contains two oscillation circuits: One for the high-frequency clock and one for the
low-frequency clock. Power consumption can be reduced by switching of the standby controller to low-power
operation based on the low-frequency clock.
between the XIN/XOUT and XTIN/XTOUT pins respectively. Clock input from an external oscillator is also
possible. In this case, external clock is applied to XIN/XTIN pin with XOUT/XTOUT pin not connected.
The data memory contents become unstable when the power supply is turned on; therefore, the data memory
The clock generator generates the basic clock which provides the system clocks supplied to the CPU core
The high-frequency (fc) clock and low-frequency (fs) clock can easily be obtained by connecting a resonator
