*Maximum length of antenna switch pattern*

Type: ``int``

Help
====

Defines maximum length of antenna switch pattern that controller
is able to store. For nRF5x-based controllers, the hardware imposes
the value is within range 3 to 40, where last value is maximum.
For general use cases Bluetooth Core 5.1 spec. required the value
to be within range 2 up to 75.
