Programming Examples
This section shows an example of typical usage of the SPORT peripheral
in conjunction with the DMA controller. See
Listing 12-4 on page
The SPORT is usually employed for high-speed, continuous serial trans-
fers. The example reflects this, in that the SPORT is set-up for
auto-buffered, repeated DMA transfers.
Because of the many possible configurations, the example uses generic
labels for the content of the SPORT's configuration registers
( and
SPORTx_RCRx
value is given in the comments, but for the meaning of the individual bits
the user is referred to the detailed explanation in this chapter.
The example configures both the receive and the transmit section. Since
they are completely independent, the code uses separate labels.
