12 OSD CONTROL REGISTERS
The functions of the OSD are controlled by Derivative Registers 22, 23, 33, 34, 35, 36 and 37. An overview of the function
of each register is given in Table 16. A full description of each register is given in Sections 12.1 to 12.7.

FUNCTION
CON1
Derivative Register 22
22
This register is used to enable PWM8; the I
2
C-bus lines; the
ADC channel and the VOW0 and VOW1 lines.
This register selects the output polarity of the PWM outputs
and also enables and selects the VSYNCN interrupt.
This register selects the blinking frequency and the active
ratio of the blinking frequency for the OSD.
This register selects the 4 display modes; the active state of
HSYNCN and VSYNCN inputs and the output polarity of the
FB and VOW0 to VOW2 outputs. It also enables/disables the
OSD clock.
This register selects the vertical starting position of the
display row.
This register selects the horizontal starting position of the
display row.
This register selects the background colour in Frame
shadowing mode.
