This LSI has an on-chip clock pulse generator that generates the system clock (φ), the bus master
clock, and internal clocks. The clock pulse generator consists of a main clock oscillator, duty
adjustment circuit, clock select circuit, medium-speed clock divider, bus master clock selection
circuit, subclock oscillator, waveform shaping circuit, PLL (Phase Locked Loop) circuit, and USB
operating clock selection circuit. A block diagram of clock pulse generator is shown in figure
19.1.
The frequency of the main clock oscillator can be changed by software by means of settings in the
low-power control register (LPWRCR) and system clock control register (SCKCR). PLL 48-MHz
clock can be selected by software by means of setting the USB control register (UCTLR). For
details, refer to section 14, Universal Serial Bus (USB).
