The omux architecture consists of 2 main blocks as shown in Figure 19.

OMUX_CTRL7

0C37

R/W

[7]

1: invert RSDS clock 1 (RSDS data pair

12)

R/W

[6]

0*: normal LVDS PLL clock if LVDS

mode (normal)

1: invert LVDS PLL clock if LVDS mode,

or invert RSDS clock 0 (RSDS data pair

21) if RSDS mode

R/W

[4]

1: invert LVDS output DE

R/W

[1]

[0]

TCON remapped to PWM

TCON[1] = pwm_a enable

TCON[0] = pwm_b enable

OMUX_HALF_LINE_L

OMUX_HALF_LINE_U

0C38

0C39

R/W

[7:0]

[3:0]

RSDS split buffer half line address =

out_hpixel/2.

out_hpixel has to be multiples of 4.

E.g. for SXGA panel (1280) the value is

640

OMUX_TEST

0C3A

R/W

[1]

1: enable RSDS debug mode

R/W

[0]

1: enable LVDS debug mode
