Macro for defining an SPI transaction manager instance.

This macro allocates a static buffer for the transaction queue. Therefore, use it in only one place in the code for a given instance name.

The queue size is the maximum number of pending transactions not counting the one that is running. For an empty queue with size of for example 4 elements, it is possible to schedule up to 5 transactions.

Parameters

[in]	_name	Name of the instance to be created.
[in]	_queue_size	Size of the transaction queue (maximum number of pending transactions).
[in]	_spim_inst	Index of the SPIM hardware instance to be used.
