HC12
ramsin - 2005-07-26 13:37:00
Hi,
Does anybody know where I can find necessary parts to start working on
HC12? I'm looking for HC12 itself, its programmer and anything which is
necessary to implement a project using M68HC12.
Thanks,

...GDB/BDM for S12X (HC12)
Mamluk Caliph - 2007-06-11 08:15:00
Hi,
I need a GDB compatible debugger for HC12 (actually PC9S12XF512MLM).
It would be great is if such a device is a stand-alone TCP/IP based
unit. Any other solution that would support a Linux host & GNU tool-
chain is also interesting.
Cheers

Hi all,

In short, MC9S12NE64 - based will be a card collecting

there are diffrent ways to interprete a banking address

and others see it as 4 Mbyte with "holes" inside becouse
