The INFRQR is an 8-bit write-only register for modifying the internally generated Hsync and
Vsync frequency to reduce the color-bleeding or jitter of OSD in PAL, MPAL, or NPAL mode or
when the non-interlaced text display mode is selected in the OSD. When reset, the INFRQR is
initialized to H'10.
Bits 7 and 6
Vsync Frequency Selection (VFS2 and VFS1): Select the Vsync frequency. Here,
fh indicates the Hsync frequency in each TV format.
