6.2 Configuration of Clock Generator
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
(3) Internal low-speed oscillation clock (clock for watchdog timer)
Remark f
The clock generator includes the following hardware.
Note
Control registers
Oscillators
• Internal low-speed oscillator
This circuit oscillates a clock of f
clock always starts operating.
Oscillation can be stopped by using the internal oscillation mode register (RCM) when “internal low-speed
oscillator can be stopped by software” is set by option byte.
The internal low-speed oscillation clock cannot be used as the CPU clock. The following hardware operates with
the internal low-speed oscillation clock.
• Watchdog timer
• TMH1 (when f
The 78K0/KB2 is not provided with an XT1 oscillator (subsystem clock).
