(*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 =B5C is a 16-bit controller... ?!
I am very thankful for any constructive suggestion what-so-ever!

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