3.1.4 CONFIGURATION
3.1.4.1 Video Mode Versus Command Mode
MIPI DSI Master Block supports two modes, namely, Video mode and Command mode.
3.1.5 DUAL DISPLAY VERSUS SINGLE DISPLAY
3.1.5.1 Dual Display
MIPI DSI Master supports dual display configuration in Command mode only, that is, both main and sub display
image should be transmitted via i80 interface.
3.1.5.2 Single Display
For single display configuration, use video mode or command mode.
3.1.6 PLL
To transmit Image data, MIPI DSI Master Block needs high frequency clock (80MHz ~ 1GHz) generated by PLL.
To configure PLL, MIPI DSI Master comprises of SFRs and corresponding interface signals. PLL is embedded in
PHY module. You should use other PLL in SoC if it meets the timing specification.
3.1.7 BUFFER
In MIPI DSI standard specification, DSI Master sends image stream in burst mode. The image stream transmits in
high-speed and bit-clock frequency. This mode allows the device to stay in stop state longer to reduce power
consumption. For this mode, MIPI DSI Master has a dual line buffer to store one complete line and send it faster
at the next line time.
