SAA2500
Table 20
Example of a 2 byte data item.
Each data item has its own length in bytes. It is allowed to transfer less bytes than the data item length, skipping the last
one or more bytes (it is even allowed to transfer no bytes at all). It is not allowed to transfer more bytes than the item
length. This restriction does not hold for the APU coefficient item. After writing all APU coefficients (i.e. after writing all
APU coefficient item bytes), they may be rewritten by continuing writing bytes to the APU coefficient item. Writing more
than the specified number of bytes to a writeable data item or writing bytes to a read-only data item may cause the
SAA2500 to malfunction. The reading of a write-only data item yields irrelevant data.
