When you reconfigure the counter clock frequency, you cannot reconfigure the
corresponding counter phase shift settings with the same interface. Instead,
reconfigure the phase shifts in real time with the dynamic phase shift reconfiguration
interface. If you reconfigure the counter frequency, but want to keep the same
non-zero phase shift setting (for example, 90°) on the clock output, you must
reconfigure the phase shift immediately after reconfiguring the counter clock
frequency.
Post-Scale Counters (C0 to C6)
You can configure the multiply or divide values and duty cycle of post-scale counters
in real time. Each counter has an 8-bit high-time setting and an 8-bit low-time setting.
The duty cycle is the ratio of output high- or low-time to the total cycle time, which is
the sum of the two. Additionally, these counters have two control bits, rbypass, for
bypassing the counter, and rselodd, to select the output clock duty cycle.
