Figure 6. Read Operations
Note: Not servicing read operations results in deadlock. The only way to recover from a deadlock
situation is to perform a hard reset. Read operations are typically not serviced due to read
requests that are issued to a non-existent remote VLYNQ device or they are not serviced
due to trying to perform reads on the VLYNQ memory map prior to establishing the link.
Generally, you should not use read operations to transfer data packets since the serial nature of the
interface could potentially result in longer latencies.
