Reading c-counters in ALTPLL RECONFIG

893 Views

Here's a simple question for anyone who has done this I'm sure.

I've added a PLL RECONFIG mega function to my design and it works as advertised. I can write to all the registers to set the frequenies that I need, but I'd like to be able to read the counter values. I can read the N and M counters, but haven't figured out how to read the c-conters. The datasheet is quite confusing regarding the read-mode for the c-counters and I haven't found any examples for reading these counters.

Knowing how to read these isn't critical to my design so I have to move on, but it's going to bug me until I understand it.
