The FRDMFS4503CAEVB/FRDMFS6523CAEVB/FRDMFS6522LAEVB boards must
be plugged into a FRDM-KL25Z. Firmware controlling the communication with the
FS45xx/FS65xx must be loaded onto the MCU. The procedure for loading the firmware
is described in Section 8 "Appendix A: FRDM-KL25Z software loading". The FlexGUI
graphical user interface that is installed on a PC serves as the user interface to the
evaluation board (Section 9 "Appendix B: Installing the FlexGUI"). When connecting the
FRDM-KL25Z board to a PC through a USB cable, the following data exchanges are
available:
• SPI access (read and write) to FS45xx/FS65xx
• ADC readout, connected to regulators

CORE

• I/O readout, connected to IO_2 to IO_5
• FS0B/FS1B readout
• RSTB readout
• CAN generated TX signal
• LIN generated TX signal with loopback checking
The software bundle also includes an XML file containing register descriptions for the
FS45xx or FS65XX (depending on the evaluation board).This file must be installed in
order for the GUI to work properly. In addition, an optional Excel file can be created to
facilitate setting several registers at a click.
