NUMTOF
TOF Frequency
Selects the ratio between the number of counter overflows to the number of times the TOF bit is set.
NUMTOF = 0: The TOF bit is set for each counter overflow.
NUMTOF = 1: The TOF bit is set for the first counter overflow but not for the next overflow.
NUMTOF = 2: The TOF bit is set for the first counter overflow but not for the next 2 overflows.
NUMTOF = 3: The TOF bit is set for the first counter overflow but not for the next 3 overflows.
This pattern continues up to a maximum of 31.
