1) Free-running mode
When the counter value reaches 0, an interrupt is generated.
decrementing if Wrapping-operation is enabled (Timer0Control<TIM0OSCTL> = 0). The
maximum value is 0x000000FF for the 8-bit counter and 0x0000FFFF for the 16-bit
counter.
0x0000003F.
Operation Descriptions
channels operate identically to Timer 0.
When the timer starts counting, the counter value decrements from the initially set value.
For the One-shot-operation (Timer0Control<TIM0OSCTL> = 1), the interrupt is
generated once.
Upon reaching 0, the counter is reloaded with the maximum value and continues
The following shows an example where the 8-bit timer counter and timer value is set to
(1) One-shot-operation
(2) Wrapping-operation
The following descriptions are based on setting examples for Timer 0. The timers of other
