Re-configure FX3 "on-the-fly"
is there any safe possibility to reconfigure the FX3-hardware by using the API CyU3PDeviceConfigureIOMatrix() in a running user-application firmware? I'd like to switch the GPIF-mode from 32bit to 16bit in the user-aaplication firmware.
The FX3 API-guide says:
"This function must be called after the CyU3PDeviceInit call from the main () function. IO matrix cannot be
dynamically changed and needs to be invoked during the device initialization."
Is that the full truth ;-) or is there a backdoor somewhere?
