7.21 VLYNQ
The DM6467T VLYNQ peripheral provides a high speed serial communications interface with the following
features.
• Low Pin Count
• Scalable Performance/Support
• Simple Packet Based Transfer Protocol for Memory Mapped Access
– Write Request/Data Packet
– Read Request Packet
– Read Response Data Packet
– Interrupt Request Packet
• Supports both Symmetric and Asymmetric Operation
– Tx pins on first device connect to Rx pins on second device and vice versa
– Data pin widths are automatically detected after reset
– Request packets, response packets, and flow control information are all multiplexed and sent
across the same physical pins
– Supports both Host/Peripheral and Peer-to-Peer communication
• Simple Block Code Packet Formatting (8-bit/10-bit)
• In Band Flow Control
– No extra pins needed
– Allows receiver to momentarily throttle back transmitter when overflow is about to occur
– Uses built in special code capability of block code to seamlessly interleave flow control information
with user data
– Allows system designer to balance cost of data buffering versus performance
• Multiple outstanding transactions
• Automatic packet formatting optimizations
• Internal loop-back mode
7.21.1 VLYNQ Bus Master Memory Map
The VLYNQ peripheral includes a bus master interface that allows external device initiated transfers to
access the DM6467T system bus. Table 7-94 shows the memory map for the VLYNQ master interface.
