It is.

All experiments I've done by ejecting the card while reading seem to
have the transfer end on thing like 0xc00, 0x800, 0x1000 etc, all
even multiples of 512 bytes.

I have also read the VHDL code, which is shows it is clearly
a byte counter.

Found another bug as well when calculating the number of bytes
left, so sent off a patch.
