From Wikipedia, the free encyclopedia. The following conventions are use throughout this manual: Motorola topic Die of Motorola It would greescale a multi core, multithreaded design using CoreNet technology, shared with the emc core. History Watches The earliest attempts to reduce the amount of power required by an electronic device were related to the development of the wristwatch.

It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a bit stack pointer, and a program counter. For those who are designing “turnkeyed” instruments, we have included a complete turnkeyed application program.

The instructions are only 16, 32, or 48 bits long, a simplification compared to the series. Later, Hirotsugu Kakugawa posted details of the ‘s new features and instructions to comp.


These ‘I’ which stands for Index registers contain memory addresses, used to store values into and read values from memory. It can recover from bus faults, allowing it to implement virtual memory.

Motorola’s 68HC11x Family of 8-bit Micro-controllers

In keeping with naming practices common to Motorola designs, the is usually referred to as the “”, pronounced “oh-two-oh” or “oh-twenty”. Member feedback about In-circuit emulation: Also, floating point intermediates are 64 bits and not 80 bits as in the and coprocessors. The 68HC11 currently has instructions.

Internally, the HC11 instruction set is upward compatible with thewith the addition of a Y index register. Motorola topic Motorola MC Where freescaoe failure may cause serious consequences, it is essential that the product designer protect freesczle and property against such consequences by incorporating redundant backup systems or safety devices appropriate to the level of risk. The was also used in other personal computers, such as th Retrieved from ” https: Let’s build off of the last example.

Microprocessors Revolvy Brain revolvybrain. Frdescale using the Y register have opcodes prefixed with the byte 0x With the introduction behind you, the next set of pages provide everything you need to know to master real-time programming on the QCard: Integrated circuits Revolvy Brain revolvybrain.

Freescale 68HC11, 68HC12, 68HC16 Books

From Free Computer Books. Instructions using the Y register have opcodes prefixed with the byte 0x In some cases, replacing th The Motorola series also termed x0, m, m68k, or 68k is a family of bit CISC microprocessors. Programs written for the HC11 are 68gc11 compatible with the HC12, which has a few extra instructions. An exhaustive list of every instruction would prove to be quite cumbersome, so I will display just a few of the basic instructions.

In a typical application, a compiler or assembler converts a program’s source code such as C or assembly language to machine code and outputs it into a HEX file.

You might then look through the C V4. In other projects Wikimedia Commons.

Member feedback about Low-power electronics: The resemblances to the HC11 core design are a deliberate move to provide an upgrade path for those 8-bit 68HC11 designs that require the increased power of a bit CPU. Motorola-Freescale-NXP processors and microcontrollers.

This manual contains the following parts: Description Motorola The had bit internal and external data and address buses, compared to the early x0 models with bit data and bit address buses.
