24/208

DocID028010 Rev 2

The DSI Host main features:

•

Compliant with MIPI® Alliance standards

•

Interface with MIPI® D-PHY

•

Supports all commands defined in the MIPI® Alliance specification for DCS:

–

Transmission of all Command mode packets through the APB interface

–

Transmission of commands in low-power and high-speed during Video Mode

•

Supports up to two D-PHY data lanes

•

Bidirectional communication and escape mode support through data lane 0

•

Supports non-continuous clock in D-PHY clock lane for additional power saving

•

Supports Ultra Low-Power mode with PLL disabled

•

ECC and Checksum capabilities

•

Support for End of Transmission Packet (EoTp)

•

Fault recovery schemes

•

3D transmission support

•

Configurable selection of system interfaces:

–

AMBA APB for control and optional support for Generic and DCS commands

–

Video Mode interface through LTDC

–

Adapted Command Mode interface through LTDC

•

Independently programmable Virtual Channel ID in

–

Video Mode

–

Adapted Command Mode

–

APB Slave

Video Mode interfaces features:

•

LTDC interface color coding mappings into 24-bit interface:

–

16-bit RGB, configurations 1, 2, and 3

–

18-bit RGB, configurations 1 and 2

–

24-bit RGB

•

Programmable polarity of all LTDC interface signals

•

Extended resolutions beyond the DPI standard maximum resolution of 800x480 pixels:

maximum resolution is limited by available DSI physical link bandwidth:

–

Number of lanes: 2

–

Maximum speed per lane: 500Mbps

Support for sending large amounts of data through the memory_write_start (WMS) and

memory_write_continue (WMC) DCS commands

•

LTDC interface color coding mappings into 24-bit interface:

–

16-bit RGB, configurations 1, 2, and 3

–

18-bit RGB, configurations 1 and 2

–

24-bit RGB
