To configure the RX CPDMA for receive operations the software must perform the following:
- Initialize the RX_HDP registers to 0.
- Enable the desired receive interrupts in the CPDMA_RX_INTMASK_SET register.
- Setup the transmit channel(s) buffer descriptors in host memory as required by CPPI 3.0
- Configure and enable the receive operation as desired in the CPDMA_RX_CONTROL register.
- Write the appropriate RX_HDP registers with the appropriate values to start packet operations.
