1. Attach the +24 V DC supply to the V
BAT
input connector on the
FRDM‑24XSMBEVB
on J8 or J1 (making sure to observe the GND and +24 V terminals). The current
capability of the +24 V supply should exceed the maximum total current that the
number of simultaneously ON loads requires.

D11, which should be illuminated.
4. Connect the KL25Z to the PC using the USB KL25Z port (left side of SW1). A window
pops up on the SPIGen GUI.
