Hello I need to interface 4MB of DRAM to a motorola DSP56364 and want to do it as cheaply as possible with the minimal amount of components. My first idea was to use an off the shelf (surplus) 4MB 30 pinn simm that you can pick up for a few bucks. The socket takes up minimal PCB real estate. The problem is they are 5V and the 56364 is 3.3V Any suggestions

I have a nasty problem where when I emulate everything works great but when I run out of flash it blows up. I've narrowed the problem down to some .asm files I have included in the project from the MSL.

Hi: I am developing a software using 8013 by using the CodeWarrior 7.2. I need to set the PWM clock rate to 3 times of the system clock in order to increase the output bandwidth/resolution. I know that this has to be done by setting the PCR bit in SIM_GPS register. However, I can't find a place anywhere in the bean inspector to make such

hi all it seems that i have a similar problem like Peter. I have 32 nodes on a CAN bus. Every 50ms each of them sends a message frame with an ID in a range from 10000 to 15000. This happens synchronously. So there is quite a long phase where the nodes are struggling for the bus. I've set the global acceptance mask register to allow message frames with
