The use-case is to send and receive about 100 Bytes every 5 msec with 460 KBaud.

The use case is, however, inter processor communication inside an embedded device. SPI is not an option (because of reduced feature set of the other processor) as well as USB, too.</P></BODY></HTML> Wed, 18 Jul 2012 16:48:42 GMT https://community.nxp.com/t5/MQX-Software-Solutions/Feature-Request-for-Kinetis-DMA-for-UARTs/m-p/178854#M2545 Fabi 2012-07-18T16:48:42Z
