Put 16 bits in e.g. register 1000 and the rest 16 bits into register
1001. Use two adjacent registers for the 32 bit and/or floating point
data.
Which 16 bits (and in what byte order) should be put into reg 1000 and
what into reg 1001 that you have to figure out yourself. The
convention varies from device to device. Some device might even expect
non-IEEE floating point formats :-).
