Setting Up DMA Parameter Registers Data Buffer Registers Figure 2-3 shows the data buffer registers for each port. These registers include: • Serial Port Receive Buffer (RXSPx). These receive buffers for the serial ports have two position FIFOs for receiving data when connected to another serial device. • Serial Port Transmit Buffer (TXSPx). These transmit buffers for the serial ports have two position FIFOs for transmitting data when connected to another serial device. • SPI Receive Buffer (RXSPI, RXSPIB). These receive buffers for the SPI ports have a single position buffer for receiving data when connected to another serial device. • SPI Transmit Buffer (TXSPI, TXSPIB). These transmit buffers for the SPI ports have a single position buffer for transmitting data when connected to another serial device. • Parallel Port Transmit Buffer (TXPP). This transmit buffer for the parallel port has two position FIFOs for transmitting data when connected to another parallel device. • Parallel Port Receive Buffer (RXPP). This receive buffer for the parallel port has two position FIFOs for receiving data when connected to another parallel device. • Input Data Port Buffers (IDP_FIFO). This receive buffer for the input data port has eight position buffers for receiving data when connected to another device. 2-28 ADSP-2136x SHARC Processor Hardware Reference for the ADSP-21362/3/4/5/6 Processors
