Moving Data Between SPORTS and
Internal Memory
Transmit and receive data can be transferred between the serial ports and
on-chip memory with single word transfers or with DMA block transfers.
Both methods are interrupt-driven, and use the same internally-generated
interrupts.
SPORT DMA provides a mechanism for receiving or transmitting an
entire block of serial data before the interrupt is generated. When serial
