// CLASS CRegInfo
//
// Description:
// Provides min, max, and default values for a register. To use this class,
// user will declare an object of this class and provide min, max and default
// values of the register.
//
// Attributes:
// int intMin - minumum value
// int intMax - maximum value
// int intDefault - default value
//
// Methods:
// Min() : return minimum value of the register
// Max() : return maximum value of the register
// Default(): return default value of the register
// OutOfRange() : check if an value is out of range
//
/////////////////////////////////////////////////////////////////////////////

// CLASS Decoder
//
// Description:
// This class encapsulates the register fields in the decoder portion of
// the Bt848.
// A complete set of functions are developed to manipulate all the
// register fields in the decoder for the Bt848.
// For Read-Write register field, "Set..." function is provided to modify
// the content of the reigster field. And either "Get..." (for more
// than 1 bit) or "Is..." (for 1 bit) function is provided to obtain the
// value of the register field.
// For Read-Only register field, only "Get..." (for more than 1 bit) or
// "Is..." (for 1 bit) function is provided to obtain the content of the
// register field.
// When there are odd-field complements to the even-field register field,
// same value is set to both odd and even register fields.
// Several direct register content modifying/retrieval functions are
// implemented for direct access to the register contents. They were
// originally developed for testing purpose only. They are retained in the
// class for convenience only and usage of these functions must be very cautious.
//
// Methods:
// See below
//
// Note: 1) Scaling registers are not implemented.
// 2) Odd-fields are set to the same value as the even-field registers
