/******************************************************************************
*
*  PARAMETER RAM (PRAM) FOR EACH PERIPHERAL
*  
*  Each subsection contains protocol-specific PRAM for each peripheral,
*  followed by the PRAM common to all protocols for that peripheral.  These 
*  structs are used as needed in the main MPC8260 memory map structure.  Note 
*  that different modes of operation will require the use of different PRAM 
*  structs, and that certain structs may overlay and conflict with the use of 
*  other PRAM areas.  Consult the MPC8260 VUser Manual for details as to what
*  is unavailable when certain protocols are run on certain peripherals.
