ADS8344 and HCS12

(*HOW*) can I connect the A/D converter ADS8344 (16-bit out) to the SPI

module of the MC9S12C32 (ChipS12 / HCS12)?

It appears quite illogical to me that a 16-bit signal can be acceppted
and understood by an 8-bit SPI modul, but I am still hoping I got
something wrong, there is a misunderstanding or even better some trick
to get around this problem?
After all this µC is a 16-bit controller... ?!


I am very thankful for any constructive suggestion what-so-ever!

Arg: Crossposting and a nerveous finger so you send the message multiple
times...

The ADS8344 needs 24/25/32 clocking steps. The 32 bit transfer can be
constucted by 4 8 bit transfers.
