You must program this register to match the clock frequency of the timestamp generator, in ticks per second. For example, for a 50 MHz clock, program
0x02FAF080. The real-time speed of the counter does not depend on the value of this register. This register reports, to the reader, the speed of the counter as programmed by the system firmware.
The CNTFID0 register characteristics are:
