5.1 Functions of Clock Generator
5.2 Configuration of Clock Generator
Control registers
Oscillators
The clock generator generates the clock to be supplied to the CPU and peripheral hardware.
The following two types of system clock oscillators are used.
The clock generator consists of the following hardware.
Main system clock oscillator
This circuit oscillates at 1.0 to 5.0 MHz. Oscillation can be stopped by executing the STOP instruction or setting
the processor clock control register (PCC).
Subsystem clock oscillator
This circuit oscillates at 32.768 kHz. Oscillation can be stopped by the suboscillation mode register (SCKM).
