Vinculum VNC1L testing

[temtronic]

Does anyone other than me, use the VNC1L for data storage? If so how do you test see if the module, not the flash drive, is available ?

I haven't used this chip but the usual thing I would do is to read a status
register and see what I got back. The VNC1L "read firmware version"
command would seem suitable for this. If you get some reasonable
number back for the version, then the chip is there.

Another way is to find a R/W register that's unimportant. In other words,
it won't hurt if you write something to it. Then try writing 0x55 and read it
back, and maybe follow with 0xAA and read it back. This assumes all bits
are read-writable. If it works, then the chip is there.
