 *  CPU Codes
 *
 *  Figure 47 shows the format of cpu code.  Some processors use the format
 *  given in Figure 47(1).  The format given in Figure 47(2) is used for all
 *  other proprietary processors.
 *
 *  The code assignment of the CPU1 region in the format given in Figure 47(1)
 *  is common to ITRON and BTRON specifications.  The same number is used in
 *  the CPU type of the standard object format of BTRON specification
 *  operating systems implemented on a TRON-specification chip.
 *
 *  When using the format given in Figure 47(2) the code used for MAKER1 is
 *  assigned by using the lower 8 bits of MAKER described in the previous
 *  subsection.  The code assignment of CPU2 is left up to each maker.

/*
 *  Assigning Version Numbers
 *
 *  The version numbers of ITRON and uITRON specifications take the following
 *  form.
 *  
 *          Ver X.YY.ZZ[.WW]
 *  
 *  where "X" represents major version number of the ITRON specification to
 *  distinguish ITRON1, ITRON2 and uITRON 3.0 specifications.  Specific
 *  assignment is as follows.
 *  
 *          "X" = 1  ITRON1 specification
 *              = 2  ITRON2 or uITRON 2.0 specification
 *              = 3  uITRON 3.0 specification
 *  
 *  "YY" is a number used to distinguish versions according to changes and
 *  additions made to the specification.  After the specification is published,
 *  this number is incremented in order "YY" = 00, 01, 02... according to
 *  version upgrades.  The first digit of "YY" is 'A', 'B' or 'C' for draft
 *  standard versions and test versions within the TRON Association before the
 *  specification have been published.
 *  
 *  The "X.YY" part of the specification version numbers is returned by spver
 *  to get_ver system call.  The corresponding hexadecimal value is used when
 *  "YY" includes 'A', 'B' or 'C'.
 *  
 *  "ZZ" represents a number used to distinguish versions related to the written
 *  style of a specification.  This number is incremented in order
 *  "ZZ" = 00, 01, 02... when there have been changes in specification
 *  configuration, reordering of chapters or corrections of misprints.  
 *  When a further distinction of the written style of specifications is
 *  desired, ".WW" may be added optionally after "ZZ".  WW will be assumed
 *  to be zero if ".WW" is omitted.
