This LSI incorporates a clock pulse generator, which generates the system clock ( ), bus master
clock, and internal clock.
The clock pulse generator consists of an oscillator, duty correction circuit, clock select circuit,
medium-speed clock divider, bus master clock select circuit, subclock input circuit, and waveform
forming circuit. Figure 18.1 shows a block diagram of the clock pulse generator.
The bus master clock is selected as either high-speed mode or medium-speed mode by software
according to the settings of the SCK2 to SCK0 bits in the standby control register. For details on
the standby control register, refer to section 19.1.1, Standby Control Register (SBYCR).
The subclock input is controlled by software according to the EXCLE bit setting in the low power
control register. For details on the low power control register, refer to section 19.1.2, Low Power
Control Register (LPWRCR).
