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.

Notes:
1. “0” to “7” correspond to the video data signal V0 to V7 respectively.
2. The most significant bit (MSB) of each video data signal is read first.
