2. Sending data from M66307 to peripheral equipment

After data for one line is stored from the system bus into the M66307,

the M66307 serially sends the data to the peripheral equipment.

There are 16 methods to send data as shown in Fig. 7. Figures 8 to

11 show the send timings for four of the 16 send method.
