Value for generating periodic events. Each time the timer has reached this time, the period event occurs
and the timer restarts.
If the increment value in ATIME_INC is given in true nanoseconds, this value is also given in true
nanoseconds.
The value should be initialized to 1000000000 (=1*109) to represent a timer wrap around of 1 second. The
increment value set in ATIME_INC should be set to the true nanoseconds of the period of clock ts_clk, hence
implementing a true 1 second counter.
