When this option is enabled, the Controller continues receiving PDUs
In the next connection event instead of entering latency
After a data packet is received.

When this option is enabled, the Controller automatically initiates a data length update
Using the appropriate data length parameters
When a PHY update or a connection interval update occurs.
