NXP ARM LPC1768 timer External Match Register and MAT0.n registers

[perdrix]

I've been trying to make sense of the docs for the External Match Register (EMR) and the related MATn.m registers and I'm suffering from a total disconnect

Please could someone who knows explain to me in simple terms how this relates to GPIO pins and how you use them.

Thanks
David

Emr is for the capture inputs. Mr (mat) is for internal counter match events.
