Hello,

    LPC1227 (122x) supports micro DMA. And according to datasheet, DMA can be used with peripheral including GPIO. But there are no any other information, how to use it, what handshaking pins should be connected, etc.
  My task - to send and receive 8-bit data via PORT0[0..7]. Are there any diagrams how to synchronyze the transface? Any code examples?
  In my case, CPU will always be master.

Thanks in advance for any info.
