WINT : Specifies the color intensity of the background window 1. Setting this bit to “0” means low
intensity.
WSHD : Enables shadowing on the window 1.
R, G, B : Specifies the color of the relative background window 1.
W2ROW, W2COL (w) : Window 2 control registers.
Row (column) start (end) address : These registers are used to specify the window 2 size.
WEN : Enables the relative background window 2 display.
WINT : Specifies the color intensity of the background window 2. Setting this bit to “0” means low
intensity.
WSHD : Enables shadowing on the window 2.
R, G, B : Specifies the color of the relative background window 2.
W3ROW, W3COL (w) : Window 3 control registers.
Row (column) start (end) address : These registers are used to specify the window 3 size.
WEN : Enables the relative background window 3 display.
WINT : Specifies the color intensity of the background window 3. Setting this bit to “0” means low
intensity.
WSHD : Enables shadowing on the window 3.
R, G, B : Specifies the color of the relative background window 3.
W4ROW, W4COL (w) : Window 4 control registers.
Row (column) start (end) address : These registers are used to specify the window 4 size.
WEN : Enables the relative background window 4 display.
WINT : Specifies the color intensity of the background window 4. Setting this bit to “0” means low
intensity.
WSHD : Enables shadowing on the window 4.
R, G, B : Specifies the color of the relative background window 4.
VERTD (w) : Specifies the starting position for vertical display. The total steps are 256, and the increment
of each step is 4 horizontal display lines. The starting position is calculated as (VERTD*4 + 1)
horizontal display lines. The initial value is 4 after power up.
HORD (w) :
Specifies the starting position for horizontal display. The total steps are 256, and the
increment of each step is 6 dots. The starting position is calculated as (HORD*6 + 49)
horizontal display dots. The initial value is 15 after power up.
CH (w) :
Defines the character vertical height, the height is programmable from 18 to 71 lines. The
character vertical height is at least 18 lines if the content of CH6-CH0 is less than 18. For
example, when the content is “2”, the character vertical height is regarded as equal to 20
lines. And if the content of CH4-CH0 is greater than or equal to 18, it will be regarded as
equal to 17. See table list in section 11.1 for detail description of this operation.
RSPACE (w) : Defines the row to row spacing in unit of horizontal line. Extra RSPACE horizontal lines will be
appended below each display row, and the maximum space is 31 lines. The initial value is 0
after power up.
OSDCON (r/w) : OSD control registers.
OSDEN = 1 Activates the OSD operation.
= 0 Disables the OSD operation.
BSEN = 1 Enables the character bordering or shadowing effect.
= 0 Disables bordering and shadowing effect.
Shadow = 1 Selects the character shadowing effect if BSEN bit is set to “1”.
= 0 Selects the character bordering effect if BSEN bit is set to “1”.
FBEN = 1 Enables the fade-in/fade-out or blending-in/blending-out effect when OSD is
