Dear all,

I'm just trying to understand UC3C ring buffer functionality.
One question I got is whether it's possible to write TCR register during PDCA channel is active...
From datasheet TCR register is generally read/ write-able. But in PDCA text it only states that the register is readable at any time???

My goal is to implement a kind of oscilloscope pre- and post trigger system.
The ADC input data should be transfered to RAM ring buffer using PCDA. When a trigger (interrupt) occures I want to reload TCR register to record a defined number of samples (post trigger).

I'm looking forward to your hints!

Regards
reini
