Adapt912B(C)32

Adapt912B32 is functionally identical to the Motorola EVB912B32 Evaluation Board-- with a few significant improvements. It is in a compact, modular Adapt12 form factor, compatible with prototyping cards, backplanes, and solderless breadboards (proto boards), making it a lot more versatile. It also includes a 5-volt regulator, a Vfp generator circuit for Flash Erase/Program voltage, and both RS485 and RS232 transceivers (jumper-selectable) on board. Like the EVB912B32, Adapt912B32 has Motorola's D-Bug12 monitor/debugger resident in Flash. This program has four jumper-selectable modes of operation, invoked when the processor comes out of reset. Modes 1, 3, and 4 require a dumb terminal, or the use of a terminal program on a host computer (PC, Mac, Amiga, workstation, etc.).

Mode Description
1)   EVB             runs the program in Flash (D-Bug12, if you haven't replaced it)
2)   JMP-EE       jumps to the start of on-chip EEPROM to execute a user program
3)   POD             D-Bug12 commands operate on a target HC12 board, connected via the BDM OUT connector;
allows you to load/modify/trace/single-step a program in a target HC12 system's Flash/EEPROM/RAM
or external memory
4)   BOOTLOAD   using a terminal program, you can erase Flash or load a program (s-record) into FLASH or EEPROM

Here are a few ways you can use Adapt912:

1) As a standalone target, you can utilize D-Bug12 to write/debug programs in the 768-byte on-chip EEPROM. Once you are comfortable working with the chip, you can write larger applications and program them into Flash (erasing D-Bug12 first). There is a small write-protected bootblock in Flash, which contains the BOOTLOADER code implemented by Mode4, above, so if you wish to re-load D-Bug12 at some later time, it is quite easy to do so. By the way, the Flash is erasable/programmable thousands of times under normal operating temperatures and voltages, so you don't have to worry about wearing it out anytime soon. A convenient switch is provided to apply Vfp when required. Since Adapt912B32 module has a Vfp generator on-board, you don't need to provide a 12V regulated supply. Any DC supply between 8 and 15 V can be used. The module draws a nominal 50 mA, so a commonly-available 9VDC adapter with a 200mA or higher rating will work fine. For portable applications, an 8.4 V or higher NiCd pack will be adequate.

2) As a Background Debug Mode (BDM) Pod, Adapt912B32 functions as an interface between a terminal and any 'HC12 board (target). Just connect the Adapt912B32 BDM OUT connector to the target board's BDM IN connector via a ribbon cable (supplied with Starter Package). The target board could be another Adapt912B32, an Adapt812, Adapt812DX, Adapt912D60, Adapt912DG128, or any other 'HC12 board that has a 6- or 10-pin BDM interface connector. The host for using the BDM Pod can be any type of dumb terminal, or any computer running a terminal program. The BDM pod will receive its 5V operating power from the target board.

(3) As an Expanded Mode combo, utilizing the Adapt912MX1 RAM+ memory expansion card. This configuration gives you a lot more memory to work with, and a lot more code development flexibility. See the Adapt912MX1 page, and Application Note for details.
