bits in combination.

CINT
(Bit 4)
RINT
(Bit 5)
As shown above, the horizontal character size is decided by using these
two bits in combination. However, unlike VZ, the surrounding area (row) is
taken over in the amount of the HZ increase, so you must keep that in mind
when changing font size. Refer to Character Size.
Character color intensity
When this bit is set to '1', the color intensity of the character on the same
row becomes high. Refer to BLINK/FINT, INTE, RINT, and CINT's
combination chart in the previous page. (Even if you change this bit, you
can't check the intensity feature on the demo board. This is because the
OSD IC's output INT is applied as the video Pre Amp's input, and the demo
board doesn't apply the OSD IC's INT output to the Pre Amp.)
Raster color intensity
When this bit is set to '1', the color intensity of the raster on the same row
becomes high. Refer to BLINK/FINT, INTE, RINT, and CINT's combination
chart in the previous page. (Like CINT given above, you can't check RINT's
feature on the demo board.)
