config BT_CTLR_CONN_ISO_RELIABILITY_POLICY
bool "CIS creation policy for reliability"
depends on BT_CTLR_CENTRAL_ISO
help
Select this option to use reliability policy for CIS creation. This
favors a CIS layout/configuration which utilizes the full range of the
Max_Transmission_Latency for maximum retransmission and payload
recovery.
config BT_CTLR_CONN_ISO_LOW_LATENCY_POLICY
bool "CIS creation policy for low latency"
depends on BT_CTLR_CENTRAL_ISO
help
Select this option to use low latency policy for CIS creation. This
favors a CIS layout/configuration which compacts payload transmission
for lowest possible latency.

bool "Application Defined Assertion Handler"
help
This option enables an application-defined sink for the
controller assertion mechanism. This must be defined in
application code as void \"bt_ctlr_assert_handle(char \*, int)\"
and will be invoked whenever the controller code encounters
an unrecoverable error.

help
Route debug GPIO toggling for the BLE Controller. Enable this when
using Bluetooth Controller Debug Pins in co-processor and the main
processor needs to setup and/or route the signals.
