• 2 pushbutton switches
• On-board speaker driven by timer or PWM for alarm, voice and music applications  
• Power-On LED indicator
• Pre-installed with D-Bug12 monitor (for AsmIDE or EmbeddedGNU) or Serial Monitor ( for CodeWarrior)
• Comes with AsmIDE and EmbbedGNU IDE under GPL (general public license) for using with D-Bug12 monitor
• Mode switch for selecting 4 D-Bug12 operating modes: EVB, Jump-to-EEPROM, BDM POD and Bootloader.  Mode indication (E,J,P,B) on the 7-segment display during power-up, no need to remember jumper setting 
• 62 of MC9S12DG256 I/O pins are accessible on male header connectors for user applications 
• BDM-in connector to be connected with a BDM from multiple venders for debugging
• BDM-out connector for making this board as a HCS12/9S12 BDM POD programmer. No extra hardware needed.
• Fast SPI expansion port for interfacing external SPI devices
• Reset switch
• Abort switch for stopping program when program is hung in a dead loop
• Besides the on-chip 256K flash, 12K RAM and 4K EEPROM, the MC9S12DG256 MCU also includes the following on-chip peripherals:
  
  • 3 SPIs
  • 2 SCIs
  • 2 CANs
  • I²C interface
  • 8 16-bit timers
  • 8 PWMs
  • 16-channel 10-bit A/D converter
