General-Purpose Timer Load Value. This field is the value to be loaded into the GPTCNT countdown timer
on a reset action. This value in this register represents the time in microseconds minus 1 for the timer
duration.
Example: for a one-millisecond timer, load 1000 Note: Max value is 0xFFFFFF or 16.777215 seconds.
General-Purpose Timer Run.
This bit enables the general-purpose timer to run. Setting or clearing this bit will not have an effect on the
GPTCNT except if it stops or starts counting.

General-Purpose Timer Reset.
Writing a 1 to this bit will reload the GPTCNT with the value in GPTLD.
0
1
STOP — Timer stop.
RUN — Timer run.
NOACTION — No action.
LOADCOUNTER — Load counter value.
