In Figure 18-28, the external device is master during C1 and C2. It releases bus control in
C3 by asserting BG to the MCF5307. During C4 and C5, the MCF5307 is implicit master
because no internal access is pending. In C5, an internal bus request becomes pending,
causing the MCF5307 to become explicit bus master in C6 by asserting BD. In C7, the
external device removes the bus grant to the MCF5307. The MCF5307 does not release the
bus (the MCF5307 continues to assert BD) until the transfer ends.
Chapter 5, “Debug Support is a MCF5307 bus arbitration state diagram. States are
described in Table 18-6.

The MCF5307 can start a transfer in the clock cycle after BG
is asserted. The external master must not assert BG to the
MCF5307 while driving the bus or the part may be damaged.
