Physical device drivers

Note: PDD layer is available only for Kinetis and ColdFire+ family microcontrollers.

Physical Device Drivers (PDD) is a software layer that provides set of methods for accessing microcontroller peripheral configuration registers.

PDD methods abstract from:

What kind of registers are available
How registers are organized
How they are named

PDD header files are located at: {CodeWarrior}\Processor Expert\lib\{MCU}\pdd. Each file contains a definitions of PDD methods for one microcontroller peripheral. Basic PDD methods are implemented by macros and do not provide any additional functionality like register masking, shifting, etc.
