Data Transmit with the Peripheral DMA Controller
Data Receive with the Peripheral DMA Controller
To assure correct implementation, respect the following programming sequences:
1. Initialize the Peripheral DMA Controller TX channel (memory pointers, size, etc.).
2. Configure the master mode (DADR, CKDIV, etc.).
3. Start the transfer by setting the Peripheral DMA Controller TXEN bit.
4. Wait for the Peripheral DMA Controller end TX flag.
5. Disable the Peripheral DMA Controller by setting the Peripheral DMA Controller TXDIS
