ADSP-SC58x SPI Register Descriptions
Received Word Count Reload Register
The
register holds the receive word count value that the SPI loads into the
SPI_RWCR
transfer count decrements to zero. To prevent the SPI from reloading the counter, use zero for the reload count val-
ue. The
SPI_RWCR
register should only be changed when the counter is disabled.
