2.7 User Configurable Settings

The MCF8329RRYEVM includes a variety of user-selectable jumpers, switches, and resistors on the entirety of the evaluation board to configure settings. A summary all of these configurable settings is provided in Table 2-2.

Table 2-2 Description of User-Selectable Settings on MCF8329RRYEVM
Designator Setting Name Description Layer Position Function
J8 3V3_SEL Select 3.3V source for MCU power Top J8 = 3V3EXT External
J8 = 3V3COM From FTDI (30mA)
J6 5V_SEL Select 5V source for FTDI power Top J6 = 5V_EXT External
J6 = 5V_USB From USB power (500mA)
