Detailed Description

This module provides the interface for the protocols to communicate with a coexistence arbitrator, Packet Traffic Arbitrator, PTA.

Concurrency model of this module: Each function defined in this interface may be called from any execution context (thread, including preemptive thread in operating system, or handler). However, none of the functions is re-entrant. It is responsibility of API user to ensure that even if one function is preempted by other execution context, the other execution context does not call preempted function.

It is not allowed to call a function defined in this module while the same function is called from another preempted context. It is allowed to call any function defined in this module while any other is preempted. It is allowed to call any function defined in this module from mpsl_cx_cb_t implementation. Callback function mpsl_cx_cb_t called from this module may be called from thread or handler context. But it never preempts itself.
