2.16.18 Scan Mode
This microcomputer has the bi-scan mode for corresponding to HSYNC of double speed frequency. In the
bi-scan mode, the vertical start display position and the vertical size is two times as compared with the
normal scan mode. The scan mode is selected by bit 1 of the OSD control register 1 (refer to Figure
2.16.3).
