Reserved bits. Write as 0.
Correction counter wrap around value.
Correction period. Defines after how many clock cycles (ts_clk) the correction counter should be reset and
trigger a correction increment on the timer.
The amount of correction is defined in ATIME_INC(12:8) (see below). E.g. setting the increment amount to
zero will stop the timer for one clock cycle, slowing it down. Larger values can be used to speed up the timer.
A value of 0 disables the counter and no corrections will occur.
Note: This value is given in clock cycles, not in nanoseconds as all other values.
