Hello,

did I understand right:
With the LPC1778 I can't use a DMA with peripheral UART0 (transmit) and UART3 (transmit) at the same time?
Thanks for answer

incredible but true! A lot of combinations of DMA requests are not possible because always two requests share one bit!
Why? I don't know, in this register are 16 bits reserved!
Very bad design! The DMA loss a lot of his power!
