Features
The ITMC9S12H256 is an evaluation or development board for the Motorola MC9S12H256
microcontroller. iSYSTEM MC9S12H256 ActivePOD (in-circuit emulation) or HC(S)12 BDM debugger
(on-chip emulation) can be connected to the board.
ActivePOD is connected directly to the board replacing the MC9S12H256 CPU piggyback. When BDM
debugger is connected, MC9S12H256 CPU piggyback must be connected to the target and a
standard BDM port is provided for the development tool.
