When I read "Kinetis SDK v.2.1 API Reference Manual", as the read box in below, is should be "UART1"
Thank you for pointing out the typo, I will notify the DOC team of modifying it.
The correct prototype of the function is:
status_t UART_TransferSendNonBlocking (UART_Type base, uart_handle_t handle, uart_-transfer_t xfer)
