    1. Introduction This user guide details the setup and configuration of the Freescale MPC5748G customer Evaluation Board (hereafter referred to as the EVB). The EVB is intended to provide a mechanism for easy evaluation of the MPC5748G family of microcontrollers, and to facilitate hardware and software development.

  • Page 87 Daughter Card Connectors (Plugs) Notes: Connectors on Main board (Shown for reference) - there was no neat way to fit these connectors onto a B sized sheet so unfortunately the sheet size has been increased to C so will need to be printed on larger paper. - The Crystal Signals are NOT routed via the daughtercard connectors - The Specific MCU power pins are not routed via the daughter card however the jumpered MCU supply lines are brought up from the main board (see the top pins of the connector on the left)
