Data Transfer Operation
Note the following characteristics of a basic read:
States are described in Table 18-4.
18.4.4 Write Cycle
During a write cycle, the MCF5307 sends data to memory or to a peripheral device. The
write cycle flowchart is shown in Figure 18-7.

• In S3, data is made available by the external device on the falling edge of BCLKO
• In S4, the external device can stop driving data after the rising edge of BCLKO.
• For a read cycle, the external device stops driving data between S4 and S5.
