OSCILLATOR CIRCUITS
OVERVIEW
The KS57C2308/C2316 microcontroller has two oscillator circuits: a main system clock circuit, and a subsystem
clock circuit. The CPU and peripheral hardware operate on the system clock frequency supplied through these
circuits. Specifically, a clock pulse is required by the following peripheral modules:
— LCD controller
— Basic timer
— Timer/counter 0
— Watch timer
— Clock output circuit
— Serial I/O interface
CPU Clock Notation
In this document, the following notation is used for descriptions of the CPU clock:
fx
Main system clock
fxt Subsystem clock
fxx Selected system clock
