Summery for DSI

DSI is a Lane-scalable interface

• One Clock Lane
• One to Four Data Lanes

Transmission Mode

• High-Speed signaling mode (differential signal) (100mV~300mV)
• Low-Power signaling mode (single-ended signal) (0V~1.2V)  - For returning data, only use Data Lane 0 in LP Mode

Packet Types

• Short Packet：4 bytes (fixed length) - Data ID (1byte) + Data0 (1byte) + Data1 (1byte) + ECC (1byte)
• Long Packet：6~65541 bytes (variable length) - Packet Header (4 bytes) + Data Payload (0~65535 bytes) + Packet Footer (2 bytes)

Operation Mode
Command Mode (Similar to MPU IF)

• Automatic mode
• DSI PHY TE trigger
• CMOS TE line

Video Mode (Similar to RGB IF)

• Non-Burst Mode with Sync Pulses
• Non-Burst Mode with Sync Events
• Burst Mode
