Data transfer
Scanning video data is transferred to the host computer trough video data signal line V0 to V7 in parallel synchronized with VCL.
Transfer sequence
Scanning is performed as sown in Figure 3.3, and the scanning data is assigned to the video data signal as shown in Figure 3.4. The scanning data is sent to the host computer in order of scanning.
