I think I may have found a typo in the user manual for the LPC802 (UM11045, Rev 1.4, 2018). The USART diagram (Fig 21) mentions DMA for transmission and reception. I thought that the LPC802 didn't have DMA.
Can you confirm?
You are right, the LPC802 does not have DMA module. I have checked the Fig 21 USART block diagram, the so-called "Transmit DMA request" and "Receive DMA request" are typo, I will tell the documentation to modify the doc UM1105.
Thank you for pointing out the typo.
Hope it can help you
