PPS0_Interval

The PPS0 Interval register contains the number of units of sub-second increment value between the rising edges of PPS0 signal output (ptp_pps_o[0]).

These bits store the interval between the rising edges of PPS0 signal output in terms of units of sub-second increment value. You need to program one value less than the required interval. For example, if the PTP reference clock is 50 MHz (period of 20ns), and desired interval between rising edges of PPS0 signal output is 100ns (that is, five units of sub-second increment value), then you should program value 4 (5 -1) in this register.
