timer driven DMA

28 Mar 2010

I want to use DMA to write out bytes at 10-20MHz

Page 5 of the User Manual (UM10360 - LPC17xx User manual - Rev. 01 — 4 January 2010)

says

Four general purpose timers/counters, with a total of eight capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.

But I can't find any more information on how to do it.
