This LSI incorporates a clock pulse generator which generates the system clock (φ), internal clock,
bus master clock, and subclock (φSUB). The clock pulse generator consists of an oscillator, duty
correction circuit, system clock select circuit, subclock input circuit, and subclock waveform
forming circuit. Figure 25.1 shows a block diagram of the clock pulse generator.
The subclock input is controlled by software according to the EXCLE bit and the EXCLS bit in
the port control register (PTCNT0) settings in the low power control register (LPWRCR). For
details on LPWRCR, see section 26.1.2, Low-Power Control Register (LPWRCR). For details on
PTCNT0, see section 7.3.1, Port Control Register 0 (PTCNT0).
