Feature

Feature Specification Number.

Feature Specification NumberIdentifies the specific feature set and capabilities available in this PORT peripheral implementation. Different feature numbers indicate different hardware capabilities and supported functions.

功能規格編號，標識此PORT周邊實現中可用的特定功能集

• Bit Field: [15:0] of VERID register
• Width: 16-bit unsigned integer
• Indicates available peripheral features and capabilities
• Used for feature detection and capability checking
• Different values represent different hardware configurations

註

Feature number is implementation-specific and design-dependent

Higher numbers do not necessarily indicate more features

Use lookup tables or documentation to interpret feature sets

Critical for software adaptation to different hardware variants

Detection:

Version version;
version = *reinterpret_cast<Version*>(&port->verid);
 
switch(version.feature) {
  case 0x0000: // Basic implementation
    // Configure for basic feature set
    break;
  case 0x0001: // Enhanced implementation
    // Configure for enhanced features
    break;
  default:
    // Unknown or newer feature set
    break;
}
