7.3.2 ULPS

The SN65DSI85 supports the MIPI® defined ultra-low power state (ULPS). While the device is in the ULPS, the CSR registers are accessible via I2C interface. ULPS sequence should be issued to all active DSI CLK and/or DSI data lanes of the enabled DSI Channels for the SN65DSI85 enter the ULPS. The Following sequence should be followed to enter and exit the ULPS.

  1. Host issues a ULPS entry sequence to all DSI CLK and data lanes enabled.
  2. When host is ready to exit the ULPS mode, host issues a ULPS exit sequence to all DSI CLK and data lanes that need to be active in normal operation.
  3. Wait for a minimum of 3 ms.
  4. Set the SOFT_RESET bit (CSR 0x09.0).
  5. Device resumes normal operation.(i.e video streaming resumes on the panel).
