Figure 7-103. DSI PLL Controller Overview
NOTE:
The DSI PLL controller module does not have an interface to L4 interconnect. The
programmable features are managed by registers mapped into the DSI protocol engine.

DSI PLL Controller Architecture
The DSI PLL is an ADPLLM module. The pixel clock (PCLK) frequency range is 2 to 68.25 MHz. This may
be divided by 2. This is performed by setting the DSS.
DSI_PLL_HIGHFREQ bit to 1.
shows the internal DSI PLL reference diagram.
