SPI stream I/O usage in PSP on TMS320DA828

Hi,

We are trying to use DA830's PSP v2.00.01 for our TMS320DA828 custom board.
We are trying to use SPI using stream I/O along with the rest of the application.
We have already ported the PSP for our custom da828 board.
It is mentioned in BIOS PSP userguide about SPI that--
/-------------------------
Note: Since the SPI data transfer operation is a transceiver operation, only
“Stream_write” API is used for both write and Read operations. Also note that the
channel will also be created only in DriverTypes_INOUT mode.
/-------------------------

Can somebody please answer our doubt:
Should we use only stream_write or can we use issue/reclaim model also?
Given an option we want  to use issue/reclaim model since it is mentioned that
stream_write does not work in a multitasking environment. (We want other tasks
to run when SPI tasks are running)

 Thanks and Regards,
Rajaram
