Description of Operation
The secondary
which pair well with stereo serial mode. Multiple I
be transmitted or received using a single SPORT. Note the primary and
secondary pins are synchronous, as they share clock and
sync) pins. The transmit and receive sides of the SPORT need not be
synchronous, but may share a single clock in some designs. See
Figure 19-3, which shows multiple stereo serial connections being made
between the processor and an AD1836 codec.
