h)
Since one stage of the receive FIFO is buffered,
[TSPIxSR]
<RLVL> becomes "1".
i)
Since
[TSPIxSR]
<RLVL> changes to "1" from "0", a receive FIFO interrupt (or receive DMA request)
occurs.
j)
Until the minimum idle time (t
d
) specified by
[TSPIxFMTR0]
<CSINT> has elapsed after TSPIxCS0 is
deasserted, serial transfer does not start and TSPIxCS0 remains deasserted. After the minimum idle time
(t
d
) has elapsed, TSPIxCS0 is asserted and serial transfer starts.
