EZ-KIT Lite Hardware Reference

ELVIS Select Jumper (JP2)

The ELVIS select jumper (JP2) configures the EZ-KIT Lite’s connection to an ELVIS station (see “ELVIS Interface” on page 1-8). When JP2 is installed, the connections to the push buttons and LED are re-directed to the ELVIS station, instead of the processor. The jumper settings are shown in Table 2-11.

ELVIS Voltage Selection Jumper (JP3)

The ELVIS voltage selection jumper (JP3) is used to select the power source for the EZ-KIT Lite. In a standard mode of operation, the board receives its power from an external power supply. When JP3 is installed, the board is powered from an ELVIS station and no external power supply is required. The jumper settings are shown in Table 2-12.
