Hi， I am using RA6T1, and I study the manual, there are two modules to transfer data, dmac and dtc, and my question is,
1, what is the main difference between these modules?
2, I am doing a application like this: transfer a 32bit data to gpt register every time gpt cnt overflow, the max frequency is 600khz, so which module I should use?
I glance over the manual, but did not get the point, so I want to get important information here, Thanks.
You are correct. Both the DMA and DTC can transfer data without the intervention of the CPU.
The DMA, of which there is a limited number of channels, will be configured to be activated via an interrupt…
