■ Word transfer with odd byte count
When DCT is set to an odd number of bytes and word transfers are used, the last transfer moves only one
byte. In the case of BAP not being decremented (i.e. it is either fixed or to be incremented) the lower byte of
the source is moved to the lower byte of the target (see Figure 4.5-3).

When BAP is to be decremented, the transferred byte is read from or written to the high byte of the word
which is referred to by BAP (see Figure 4.5-4).
