6.1 Functions of Clock Generator
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
The clock generator generates the clock to be supplied to the CPU and peripheral hardware.
The following three kinds of system clocks and clock oscillators are selectable.
(1) Main system clock
(2) Subsystem clock
Note
Remark f
<1> X1 oscillator
<2> Internal high-speed oscillator
An external main system clock (f
external main system clock input can be disabled by executing the STOP instruction or using RCM.
As the main system clock, a high-speed system clock (X1 clock or external main system clock) or internal high-
speed oscillation clock can be selected by using the main clock mode register (MCM).
• Subsystem clock oscillator
An external subsystem clock (f
external subsystem clock input can be disabled by setting PCC and OSCCTL.
This circuit oscillates at a frequency of f
XT2. Oscillation can be stopped by using the processor clock control register (PCC) and clock operation mode
select register (OSCCTL).
The 78K0/KB2 is not provided with a subsystem clock.
This circuit oscillates a clock of f
Oscillation can be stopped by executing the STOP instruction or using the main OSC control register (MOC).
This circuit oscillates a clock of f
with this internal high-speed oscillation clock. Oscillation can be stopped by executing the STOP instruction
or using the internal oscillation mode register (RCM).
