Register Description by Block
● Number of bars in C1 = PGEN_P0_MODE[4:2] +1 = 4 (bars 0 to 3)
PGEN_P0_SEQ_COL0_COL1 = 42:
● Bar 0 filters G and B components but lets R pass: this 1st bar is displayed in red
● Bar 1 filters R and B components but lets G pass: this 2nd bar is displayed in green
PGEN_P0_SEQ_COL2_COL3 = 17:
● Bar 2 filters R and G components but lets B pass: this 3rd bar is displayed in blue
● Bar 3 does not filter any of the R G B components: this 4th bar is displayed in white
PGEN_P0_SEQ_COL4_COL5 = 77: bars 4 and 5 do not filter R G B and are displayed in white.
PGEN_P0_SEQ_COL6_COL7 is don’t care, since a maximum of 6 bars is used by C0 and C1.
Across the display, 6 bars [red] [green] [blue] [white] [white] [white] (from C0 group) are now
displayed, followed by 4 bars [red] [green] [blue] [white] (from C1 group), then again 6 bars from
C0 group etc.. until the right border of the display area is reached:

4.11.2.4 Gradient Control
The gradient control registers modify the colors C0 and C1 as follows:
● PGEN_P0_GRADDELTA_R: increment the Red value by this register value
● PGEN_P0_GRADDELTA_G: increment the Green value by this register value
● PGEN_P0_GRADDELTA_B: increment the Blue value by this register value
● PGEN_P0_GRADSTEP_X: apply the increment value to each color every X horizontal pixels
● PGEN_P0_GRADSTEP_Y: apply the increment value to each color every Y vertical lines
