shown in the diagram are programmable. This timing diagram corresponds to positive polarity of the DIU_CLK signal
(meaning the data and sync signals change at its rising edge) and active-high polarity of the DIU_HSYNC, DIU_VSYNC, and
DIU_DE signal. Signal polarity of DIU_HSYNC and DIU_VSYNC are selectable via the SYN_POL register, whether
active-high or active-low. The default is active-high. The DIU_DE signal is always active-high. Also, pixel clock inversion and
a flexible programmable pixel clock delay are also supported, programmed via the DIU Clock Config register (DCCR) in the
system clock module.

In low speed mode, card clock must be lower than 400 kHz, voltage ranges from 2.7 to 3.6 V.
In normal data transfer mode for SD/SDIO card, clock frequency can be any value between 0–25 MHz.
In normal data transfer mode for MMC card, clock frequency can be any value between 0–20 MHz.
In card identification mode, card clock must be 100 kHz ~ 400 kHz, voltage ranges from 2.7 to 3.6 V.
Suggested Clock Period = T, CLK_DIVIDER (in SDHC Clock Rate register) = D, then TH = [(D + 1)/2] / (D + 1) × T where [] is
round.

DIU_CLK
DIU_DE
DIU_CLK latches data into the panel on its positive edge (when positive polarity is selected). In active mode,
DIU_CLK runs continuously. This signal frequency could be from 5 to 66 MHz depending on the panel type.
DIU_HSYNC causes the panel to start a new line. It always encompasses at least one DIU_CLK pulse.
DIU_VSYNC causes the panel to start a new frame. It always encompasses at least one DIU_HSYNC pulse.
DIU_DE acts like an output enable signal to the LCD panel. This output enables the data to be shifted onto the display.
When disabled, the data is invalid and the trace is off.
