5.2 Clock Generator
5.2.1 Clock generator function
The clock generator generates the clock pulse to be supplied to the CPU and peripheral hardware.
There are two types of system clock oscillators:
Main system clock oscillator (ceramic/crystal resonator)
This circuit generates a frequency of 1.0 to 5.0 MHz. Oscillation can be stopped by executing the STOP
instruction or by means of a processor clock control register (PCC) setting.
Subsystem clock oscillator
This circuit generates a frequency of 32.768 kHz. Oscillation can be stopped using the subclock oscillation
mode register (SCKM).
5.2.2 Clock generator configuration
The clock generator consists of the following hardware.
