Free Running Counter (FR_CNT)
This field reflects the current value of the free-running 32-bit counter. At
reset, the counter starts at zero and is incremented by one every 25MHz
cycle. When the maximum count has been reached, the counter will rollover
to zero and continue counting.
Note:
Free Running 25MHz Counter Register (FREE_RUN)
This read-only register reflects the current value of the free-running 25MHz counter. Refer to
11.2, "Free-Running Clock," on page 141
The free running counter can take up to 160nS to clear after a reset
event.
