Chapter 17 “Interrupt system”
Chapter 18 “Oscillator circuitry”
Chapter 19 “Reset”.
8.1
General
The P8xCL580 is a stand-alone high-performance CMOS
microcontroller designed for use in real-time applications
such as cordless telephone and mobile communications,
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 Memory.
The P8xCL580 contains a 6 kbytes Program Memory
(ROM; P83CL580); a static 256 bytes Data Memory
(RAM); 40 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, 4-channel 8-bit
A/D converter, Watchdog Timer and Pulse Width
Modulation output.
The device has two software-selectable modes of reduced
activity for power reduction:
Idle mode
; freezes the CPU while allowing the
derivative functions (timers, serial I/O, ADC, PWM) 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.
