Detailed Description

SPI transaction descriptor.

The manager stores only a pointer to this descriptor, so the descriptor, its transfers array, and any referenced buffers must remain valid until the transaction completes.

If required_spim_cfg is non-NULL it must remain valid until the transaction completes. If it is NULL, the default configuration passed to bm_spi_mngr_init is used.

If required_spim_cfg differs from the configuration currently in use, the module initializes the SPIM instance again before starting the transaction.

The documentation for this struct was generated from the following file:

bm_spi_mngr.h
