any other high-speed channel. Real-time instruction and data flow activity can be recorded
and then formatted for display on the host computer that runs the debugger software. TPA
hardware is commercially available from common development tool vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.
2.47 DSI Host (DSIHOST)
The DSI Host is a dedicated peripheral for interfacing with MIPI
®
DSI compliant displays. It
includes a dedicated video interface internally connected to the LTDC and a generic APB
interface that can be used to transmit information to the display.
These interfaces are as follows:
• LTDC interface:
– Used to transmit information in Video mode, in which the transfers from the host
processor to the peripheral take the form of a real-time pixel stream (DPI).
– Through a customized for mode, this interface can be used to transmit information
in full bandwidth in the Adapted Command mode (DBI).
• APB slave interface:
– Allows the transmission of generic information in Command mode, and follows a
proprietary register interface.
– Can operate concurrently with either LTDC interface in either Video mode or
Adapted Command mode.
• Video mode pattern generator:
– Allows the transmission of horizontal/vertical color bar and D-PHY BER testing
pattern without any kind of stimuli.
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
