meaning of hpoint in ledc_channel_config_t?

[mzimmers]

Hi -

Today I began converting from IDF v3.0 to v3.2. One change I discovered was the addition of a field hpoint to the ledc_channel_config_t struct. I can't find any documentation on it. I found an example that set hpoint = LEDC_HPOINT_HSCH0, and I tried that, but then my LED never came on. I set it to 0 and it seems to work now, but I'm curious to know more about this variable.

Thanks...
