a beginner's doubt

[sankarganesh_a]

Hi,
 I am new to this forum. I am going to use M68HC12 controller.Before starting I would like to know the following details.

Overview of the core CPU:
Architecture of the CPU:
Architecture of the Instruction Set:

Thanks in advance.

San ; Have you seen the products here ;

I downloaded the GNU C compiler-linker from one of their links ,and program in C . Dont care about instruction sets anymore ..hehe..
(not quite true..)

If you go here : http://www.datasheetarchive.com

And enter mc9s12 and search .....you will get advanced info ....

Hi San,

If you start now, you are probably going to use HCS12 and not HC12. HCS12 is 0.25µm technology with much higher performance and stability than the previous generation.

"

HCS12 (7 modules)
The course includes an overview of the HCS12 and tutorials that describe the HCS12 CPU, instruction set, resets and interrupts, FLASH and EEPROM, and BDLC.

"

Freescale Embedded Learning Centre prensents the S12=HCS12 family.

S12 is a 16 bit Van Neumann CISC architecture. To have typical abilities of a S12CPU, I advise you the HCS12 CPU V2.0 Reference Manual guide which is dedicated to the CPU and its instruction set.

Cheers,

Alban.

In addition to Alban's information on the Freescale material there are also at least 5 or 6 books on the subject in different languages. A book on the HC12 will cover the most important information on the S12, but if can get an edition that covers the S12 then that will be better. See your local book supplier for the titles that are available.

There are also professional training courses from various companies.

Finally, the MCU is widely used in University courses and various of these are available at least partially on-line
