Using the appropriate data length parameters
When a PHY update or a connection interval update occurs.

help
Reduce the latency between issuing the advertising enable command
and the actual on-air transmission by executing the advertising TX
path from IRAM.
Note: Enabling this option increases IRAM usage.
