The initial value is 0 after power up.
DWE - Enable double width. When the bit is set to “1”, the display of OSD menu can change to half resolution
for double character width, and then the number of pixels of each line should be even. The initial value
is 0 after power up.
HSP -
= 1
Accept positive polarity Hsync input.
= 0
Accept negative polarity Hsync input.
VSP -
= 1
Accept positive polarity Vsync input.
= 0
Accept negative polarity Vsync input.
PWM1, PWM0 - Select the PWMCK output frequency.
= (0, 0)
XIN frequency /8
= (0, 1)
XIN frequency /4
= (1, 0)
XIN frequency /2
= (1, 1)
XIN frequency /1
The initial value is (0, 0) after power up.
Notes :
When XIN is not present, don’ write data in any address. If data is written in any other address, a
malfunction may occur.
WSR, WSG, WSB - Define the color of shadowing on windows. The initial value is (0, 0, 0) after power up.
CSR, CSG, CSB - Define the color of bordering or shadowing on characters. The initial value is (0, 0, 0) after
power up.
CFONT - Enable 16 multi-color fonts.
= 0
Character address 240 to 255 are connected to standard ROM fonts.
= 1
Character address 240 to 255 are connected to 16 multi-color ROM fonts.
The initial value is 0 after power up.
