Hi,
I have a question about connecting Comparator with HRTIM. I am currently working on Buck Converter with Digital Peak Current Mode Control. In this kind of control I need to measure the current of the inductor and compare it with another current waveform generated by DAC (of course it is defined by proper Voltage level) and redirect comparator output to the HRTIM (in case to switch it on and off ) which is switching the power mosfet. I need to implement blanking which tells the comparator to ignore current measurement for a short period of time because of short current spikes . In datasheet I've read that COMP is directly connected to the HRTIM in order to minimalize propagation delays, but I couldn't see any examples in software which demonstrate this and actually I haven't found any functions in software which explicitly connect HRTIM to the COMP output, so I have major problem with understanding how that works.
I will be grateful for any reply.
Best regards,
Kamil
