chapters as follows:
Chapter 9 “Memory organization”
Chapter 10 “I/O facilities”
Chapter 11 “Timers/event counters”
Chapter 12 “Reduced power modes”
Chapter 13 “Standard serial interface SIO0: UART”
Chapter 14 “Interrupt system”
Chapter 15 “Oscillator circuitry”
Chapter 16 “Reset”.
8.1
General
The P80CLx1 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 Memory.
The P80CLx1 contains 4 kbytes Program Memory (ROM;
P80CL51 only); a static 128 bytes Data Memory (RAM);
32 I/O lines; two16-bit timer/event counters;
a thirteen-source, two priority-level, nested interrupt
structure and on-chip oscillator and timing circuit.
A standard UART serial interface is also provided.
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.
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.
