detailed functional description is in the following chapters:
Chapter 9 “Memory organization”
Chapter 10 “I/O facilities”
Chapter 11 “Timer/event counters”
Chapter 12 “Reduced power modes”
Chapter 13 “I
2
C-bus serial I/O”
Chapter 14 “Standard serial interface SIO0: UART”
Chapter 15 “Interrupt system”
Chapter 16 “Oscillator circuitry”
Chapter 17 “Reset”.
8.1
General
The P83CL78x is a stand-alone high-performance CMOS
microcontroller designed for use in real-time applications
such as instrumentation, industrial control, intelligent
computer peripherals and consumer products. The device
provides hardware features, architectural enhancements
and new instructions to function as a controller for
applications requiring up to 64 kbytes of Program Memory
and/or up to 64 kbytes of data storage.
The P83CL78x contains a non-volatile 16 kbyte read-only
Program Memory; a static 256 byte read/write Data
Memory; 32 I/O lines; three 16-bit timer/event counters; a
fifteen-source, two priority-level, nested interrupt structure
and on-chip oscillator and timing circuit.
The device has two software-selectable modes of reduced
activity for power reduction:
Idle mode
; freezes the CPU while allowing the timers,
serial I/O and interrupt system to continue functioning.
Power-down mode
; saves the RAM contents but
freezes the oscillator causing all other chip functions to
be inoperative.
In addition, two serial interfaces are provided on-chip:
a standard UART serial interface, and
a standard I
2
C-bus serial interface. The I
2
C-bus serial
interface has byte-oriented master and slave functions
allowing communication with the whole family of I
2
C-bus
compatible devices.
8.2
CPU timing
A machine cycle consists of a sequence of 6 states. Each
state lasts for two oscillator periods, thus a machine cycle
takes 12 oscillator periods or 1
μ
s if the oscillator
frequency (f
osc
) is 12 MHz.
