DISP_CLK_PERIOD—number of DI_CLK per one Tdicp. Resolution 1/16 of DI_CLK
DI_CLK_PERIOD—relation of between programing clock frequency and current system clock frequency
Display interface clock period average value.
ID
Display interface clock period immediate value.
DI’s counter can define offset, period and UP/DOWN characteristic of output signal according to programed parameters of the
counter. Same of parameters in the table are not defined by DI’s registers directly (by name), but can be generated by
corresponding DI’s counter. The SCREEN_WIDTH is an input value for DI’s HSYNC generation counter. The distance
between HSYNCs is a SCREEN_WIDTH.

DISP_CLK_OFFSET— offset of
IPP_DISP_CLK edges from local start
point, in DI_CLK
(0.5 DI_CLK Resolution)
Defined by DISP_CLK counter
VSYNC_OFFSET—offset of Vsync edges
from a local start point, when a Vsync
should be active, in DI_CLK
(0.5 DI_CLK Resolution).The
VSYNC_OFFSET should be built by
suitable DI’s counter.
HSYNC_OFFSET—offset of Hsync edges
from a local start point, when a Hsync
should be active, in DI_CLK
(0.5 DI_CLK Resolution).The
HSYNC_OFFSET should be built by
suitable DI’s counter.
DRDY_OFFSET— offset of DRDY edges
from a suitable local start point, when a
corresponding data has been set on the
bus, in DI_CLK
(0.5 DI_CLK Resolution)
The DRDY_OFFSET should be built by
suitable DI’s counter.
