Hi,

the current way of initializing the internal SRAM of the IFC controller only
works for older controller versions. Newer versions require a different
method. So, adding support for it.

Thereby, the result of the SRAM initialization should be checked. If it's not
successful, further commands such as read won't work.

Tested on hardware.

Thanks,
Kurt
