Section 22A Clock Pulse Generator
(H8S/2636 Group, H8S/2638 Group, H8S/2630 Group)
22A.5 Medium-Speed Clock Divider
The medium-speed clock divider divides the system clock to generate φ/2, φ/4, φ/8, φ/16, and φ/32.
22A.6 Bus Master Clock Selection Circuit
The bus master clock selection circuit selects the system clock (φ) or one of the medium-speed
clocks (φ/2, φ/4, or φ/8, φ/16, and φ/32) to be supplied to the bus master, according to the settings
of the SCK2 to SCK0 bits in SCKCR.
22A.7 Subclock Oscillator
Connecting 32.768kHz Quartz Oscillator (U Mask, W Mask): To supply a clock to the
subclock divider, connect a 32.768kHz quartz oscillator, as shown in figure 22A-8. See section
22A.3.1, “Notes on Board Design” for notes on connecting quartz oscillators.
Figure 22A-9 shows the equivalence circuit for a 32.768kHz oscillator.
