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
