10.7.6 Outline of Each Mode of TID
Each mode of TID is outlined below. TID modes can be selected from the following, only one at a time:
(1) Fixed period count mode
In fixed period count mode, the timer uses a reload register to generate an interrupt at intervals of
(reload register set value + 1).
When after setting the reload register (initial value being indeterminate), the timer is enabled (by
writing to the enable bit in software), it loads the content of the reload register into the counter
synchronously with the count clock, letting the counter start counting. The counter counts down
clockpulses and when it underflows after reaching the minimum count, the counter is reloaded
with the content of the reload register again and continues counting. To stop the counter, disable
count by writing to the enable bit. Also, an interrupt can be generated each time the counter
underflows.
The valid count value is the (reload register set value + 1).
