When the counter value becomes “0000
tents are reloaded and counting stops.
If a trigger occurs during counting, reload register’s contents are
reloaded then and counting continues.

Internal or external trigger can be selected by software.
When the counter value becomes “0000
When count start bit is cleared to “0”
While counting is stopped
When a value is written to timer Ai register, it is written to both
reload register and counter.
While counting is in progress
When a value is written to timer Ai register, it is written to only
reload register. (Transferred to counter at next reload time.)
