* - A 24 MHz oscillator circuit (Y4) is connected to the on-board
* microcontroller. This oscillator circuit functions as the controller’s
* primary oscillator. Depending on which is populated on the starter kit
* board, a 24 MHz crystal (Y1) may be used instead of Y4.
* - The starter kit also has provisions for an external secondary 32 kHz
* oscillator (Y2); however, this is not populated.
