LIN Frame Handling With The Peripheral DMA Controller
Break
Break
Break
The USART can be used together with the Peripheral DMA Controller in order to transfer data
without processor intervention. The DMA Controller uses the TXRDY and RXRDY bits, to trigger
one byte writes or reads. It always writes to THR, and it always reads RHR.
