41.6.1.1.1 Shutdown Mode

Shutdown mode is the mode with the lowest power consumption, where all analog blocks are disabled, and digital logic is reset.

To enter this mode, set bits DPHY_RSTZ and SHUTDOWNZ in the Reset and PLL Control register (DSI_DPHY_RSTZ) to ‘0’.

In Shutdown mode, the differential lines of MIPI_DNx/Px and MIPI_CLKN/P are high impedance (Hi-Z).

By default, the D-PHY is configured to work only on the lower operation range of 80-110 Mbps. If higher bit rate operation is required, the D-PHY hsfreqrange must be programmed as defined in Frequency Ranges. If the D-PHY is always expected to function at the same bit rate, this additional step can be performed while in Shutdown mode. For more information on these options, refer to Active Modes.

When DSI_DPHY_RSTZ.DPHY_RSTZ and DSI_DPHY_RSTZ.SHUTDOWNZ are set to ‘1’, the D-PHY exits Shutdown mode and starts an initialization procedure.
