On the 0H55J and 1H55J revisions of the MCF5307, the byte count register of the DMA channels can
accommodate only 16 bits. However, on the newest revision of the MCF5307, an expanded 24-bit byte count
range provides greater flexibility. For this reason, the position of the byte count register (BCR) in the memory
map depends on whether a 16- or 24-bit byte counter is chosen. The selection is made by programming
MPARK[BCR24BIT] in the SIM module.
In the new MCF5307, the 24-bit byte count can be selected by setting BCR24BIT = 1, making DCR[AT]
available. The AT bit selects whether the DMA channels assert an acknowledge during the entire transfer or
only at the final transfer of a DMA transaction.
New applications should take advantage of the full range of the 24-bit byte counter, including the AT bit. The
16-bit byte count option (BCR24BIT = 0) is kept to retain compatibility with older revisions of the MCF5307.
