TECHNOLOGY
RSPACE - Defines the row to row spacing in each unit of the horizontal line. That is, 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.
OSDEN - Activates the OSD operation when this bit is set to "1". The initial value is” 0” after power-up.
BSEN - Enables the bordering and shadowing effect.
SHADOW - Activates the shadowing effect if this bit is set, otherwise the bordering is chosen.
TRIC - Defines the driving state of output pins ROUT, GOUT, BOUT and FBKG when OSD is disabled.
That is, while OSD is disabled, these 4 pins will drive LOW if this bit is set to “1”, otherwise these
pins are in high-impedance state. The initial value is “0” after power-up.
BLANK - Forces the FBKG pin output to HIGH while this bit is set to "1".
WENCLR - Clears all WEN bits of window control registers when this bit is set to "1". The initial value is
“0” after power-up.
RAMCLR - Clears all ADDRESS bytes of display registers when this bit is set to "1". The initial value is
“0” after power-up.
FBKGC - Defines the output configuration for FBKG pin. When it is set to "0", the FBKG outputs during
the display of characters or windows, otherwise, it outputs only during the display of charac-
ters.
TEST -
= 0
= 1
Normal mode.
Test mode, not allowed in applications.
FBKGP - Selects the polarity of the output pin FBKG.
=
1
Positive polarity FBKG output is selected.
= 0
Negative polarity FBKG output is selected
.
The initial value is “1” after power-up.
PWMCK - Selects the output options to the HTONE/PWMCK pin.
= 0
HTONE option is selected.
= 1
PWMCK option is selected with 50/50 duty cycle and is synchronous with the input
HFLB. The frequency is selected by PWM1, PWM0 as shown in table 4.
The initial value is “0” after power-up.
DWE - Enables double width. When the bit is set to “1”, the display of the OSD menu can change to half
resolution for double character width, and then the number of pixels of each line should be even.
HSP -
= 1
Accepts positive polarity Hsync input.
