Steve, Actually, when the MC9S12DG256 operates in expanded mode, and the Flash is secured, the Flash indeed cannot be accessed. This is in order to protect ...

Hi, I'm new to HC12, however I have some experience in other microcontrollers. Recently I've got the M68KIT912UF32 and I'm trying to implement composite USB ...

Hi Doron; Yup, I was afraid that was what the answer would be. It really seems like a poor design decision on the part of Motorola to prevent the use of the...

Hi Robert, We've been using the CW/Hiware C++ compiler for 5? years now. It is a decent product. There are a few bugs, a few limitations, but overall it...
... Hey, Happy New Year to you too. I just wanted to clarify two terms that might be easily confused. I notice that "start vector" and "start address" sound...
... Woa, maybe you are under the illusion that data on the bus is separate from program execution. Maybe that's possible in MCU design, but I think far from a...
Hi, rather than debug your code, here is working spi code: // initialization of spi SPI0CR1 = 0x1C; // master mode , polarity high, phase even SPI0BR = 0x00;...
Hi Amir, Entering low power mode can be tricky. What you need to look out for is the scenario where an interrupt happens right before the wait instruction....
Hi, We haven't made many changes to the 8/16 bit C++ compilers in the past few years. However our future plans is to use a more modern CodeWarrior C++ compiler...
It seems to me, if the uP is secure, any code on the external bus can only be executed if the secure code calls it. If the external bus only has data or...

Mike, The proper way to look at this matter is through the eyes of a potential hacker. Let's assume a Nomal Single-Chip application that uses a secured HCS12...

Doron, If the programmer of a secured normal single-chip application never references external memory, how can a hacker inject some data? If the programmer of...

Hi All,
I am working on a system that has a raster display, but no built in fonts. I basically want to get some debugging info on the display, but I need a...
