Function resolveSiiCategoryType

Resolve a raw SII category type value into a normalized SiiCategoryType.

Returns

Resolved category type, or undefined if not recognized.

Remarks

• The SII specification defines both fixed category IDs and value ranges:

  Mapped ranges:

  • 0x0001–0x0009 → DEVICE_SPECIFIC
  • 0x0800–0x1FFF → VENDOR_SPECIFIC
  • 0x2000–0x2FFF → APPLICATION_SPECIFIC
  • 0x3000–0xFFFE → VENDOR_SPECIFIC

• For values outside these ranges, a direct enum lookup is attempted:

  • Matches known categories such as STRINGS, GENERAL, FMMU, etc.

• The END marker (0xFFFF) is handled via direct enum lookup.

Note

• Range-based values are normalized to a single enum representative (e.g. all vendor-specific values map to VENDOR_SPECIFIC).
• The original numeric value is not preserved.
• Unknown values return undefined and should be treated as unsupported categories.
