The interval register (PITMR) holds the value that is loaded
into the PIT counter on terminal count. The PIT counter is a
down counter.
The Programmable Interval Timer resolution is configurable.
For example:
TCAPCLK divide by x of CPU clock (for example TCAPCLK
divide by 2 of a 24 MHz CPU clock will give a frequency of
12 MHz)
ITMRCLK divide by x of TCAPCLK (for example, ITMRCLK
divide by 3 of TCAPCLK is 4 MHz so resolution is 0.25
μ
s)

The Timer Capture clock can be sourced from an external
clock, Internal 24 MHz Oscillator or the Internal 32-KHz Low-
power Oscillator. A programmable pre-scaler of 2, 4, 6, or 8
then divides the selected source.
