Overview: Adapt9S12DP256 is a compact, modular implementation of Motorola's flagship 9S12DP256C microcontroller chip.  The HCS12 family is backward-compatible with 68HC12 (and 68HC11), and utilizes the latest process technology.  By shrinking feature size, more functionality can be put on a chip, reducing power consumption and cost, while increasing operating speed.  Adapt9S12DP256 is an ideal low-cost platform that brings these advantages within easy reach of engineers, students, and hobbyists.  The flexible design of the entire "Adapt" series microcontroller products accomodates all facets of training, evaluation, development, prototyping, and even volume production.

Description:

Adapt9S12DP256 is a compact, modular "AdaptS12" form factor board, compatible with an entire range of application cards, prototyping cards, and backplanes, and usable with solderless breadboards ("proto boards"). It includes all necessary support circuitry for the MCU, as well as a 5-Volt regulator, RS232, RS485, and CAN transceivers on-board.

Here are a few ways you can use Adapt9S12DP256:

- RAM-based code development using DBug12 monitor/debugger
    Using the Flash-resident DBug12 supplied, you can quickly load programs into the user portion of on-chip RAM or EEPROM and run them.  With this method, you will have a limited amount of program memory space, but you'll still be able to use interrupts because DBug12 implements a RAM-based pseudo-vector table.   Other useful debugging features available in this configuration:  insert breakpoints, examine/modify memory and registers, disassemble a range of memory, and perform line-by-line assembly.  Get the DBug12 Reference Guide, below, for more details.

- EEPROM-based code development using on-chip bootloader
    Using the Flash-resident DBug12 supplied, you can quickly load programs into the user portion of on-chip EEPROM and run them.  With this method, you will have a limited amount of program memory space, but you'll still be able to use interrupts because DBug12 implements a RAM-based pseudo-vector table.   Other useful debugging features available in this configuration:  insert breakpoints, examine/modify memory and registers, disassemble a range of memory, and perform line-by-line assembly.  You can also jumper for Jmp-EE mode and have your program run automatically, upon reset.  Get the DBug12 Reference Guide, below, for more details.

- Flash-based code development using on-chip bootloader
    With the Flash-resident bootloader portion of DBug12, you'll be able to load your program into Flash via the serial port using any terminal program, at baud rates up to 115K.  The entire 256K Flash can be programmed in under one minute!  Just send your .s19 file, move the Mode Select jumpers to EVB mode, and press reset when you're done.  Your code runs from Flash, and interrupts are supported (via Flash-based pseudo vectors, since the D-Bug12 bootloader resides in the vector space of the MCU).  A program you load into Flash this way will run every time you apply power or reset the board in Flash Mode.  In this mode, the Monitor portion of DBug12 is erased (you can always load it back in again later if you need it).

- Flash-based code development using a BDM pod
    If you want to take advantage of the debug/monitor functions of DBug12, but you'd like to use all the Flash for your program, you can use a BDM pod (such as MicroBDM12SX) to erase and load Flash with your program.  The entire 256K Flash can be used, because the Flash-resident bootloader is no longer needed (therefore pseudo-vectors aren't required either).  Just use the FBULK and FLOAD commands to erase and load your programs.

- Low-cost Solution for C source-level code debugging with ICC12, NoICE12, and a MicroBDM12SX pod
    Now you can take advantage of the debug/monitor functions of NoICE12 to perform source-level debugging with ImageCraft's ICC12 C compilers, using our MicroBDM12SX.  This combination offers the lowest-cost toolchain on the market!

- transform Adapt9S12DP256 into a Super BDM pod!
    Plug a small circuit board onto a section of the I/O connector, set DBug12's Mode Select jumpers, and your module becomes a BDM pod equivalent to MicroBDM12SX, so you can erase load or debug another module (or any HC12 target, for that matter).  Also works with NoICE12 !
