Function Documentation

nx_spi_async_owner_executor_port()

nx_owner_executor_port_t nx_spi_async_owner_executor_port	(	nx_spi_async_owner_executor_t *	executor,
		const nx_spi_port_t *	port )

Bind one async-capable bus to an explicit owner executor.

Parameters

[out]	executor	Fresh storage with no previous outstanding loans.
[in]	port	Initialized controller exclusively owned by this executor; direct clients and other owners must quiesce.

Returns

Valid executor port, or a zero port for incomplete methods.

Note

Startup/task context. Operations use nx_spi_owner_operation_t endpoints on this bus only; membership is checked before admission. No polling fallback is selected. Controller and executor remain live through drain, control acknowledgement and observer exit. QUARANTINED retains both buffer loans. Hardware stop and IRQ/notification destruction are explicit external steps after owner shutdown, not part of this bind.
