This microcomputer has the bi-scan mode for corresponding to H
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).
The form of R, G, B signal output is controlled by bit 4 of the clock register and bit 2 of the OSD control
register 2 as the table below.
