MC9S12P Basic System

Hi, 

 

is anywhere something like a Recommended System Connections or Recommended PCB Layout ? It can be found in datasheets of many Freescale microcontrollers, but not for the S12P. Maybe is there other microcontroller with the same recommended connections? 

 

Any help would be appreciated! 

 

Thanks in advance.

 

Michael

Don't know your HW board revision but let see attach for my board if it helps.

I would advise against a 100nF decoupling cap on the reset line, I've encountered lots of problems with that in the past, for various S12 devices. The S12 apparently wants a pretty steep reset edge. 100pF or 47pF are probably better values. (And the BKGD line should have a similar cap.)
