The TAiS bit (i = 0 to 4) in the TABSR register is set to 0 (count stops) after reset. Set the TAiS bit to 1
(count starts) after selecting timer operating mode and setting the TAi register.
The following occurs when the TAiS bit in the TABSR register is set to 0 (count stops) while counting.
One-shot timer is operated by an internal count source. When an external trigger is selected, a maximum of
one count source clock delay occurs between the trigger input to the TAiIN pin and the one-shot timer
output.
The IR bit becomes 1 when one of the following procedures are used to set timer operating mode.
To use the timer Ai interrupt (IR bit), set the IR bit to 0 after one of the above setting has done.
When a retrigger occurs while counting, the contents of the reload register is reloaded after the counter
decrements by one, and continues counting.
To generate a retrigger while counting, wait 1 count source clock cycle or more after the last trigger
generation.
When an external trigger input is used to start counting in timer A one-shot timer mode, do not provide an
external retrigger input for 300 ns before a timer A counter value reaches 0000h. The external retrigger may
be ignored.

The counter stops counting and the contents of the reload register is reloaded.
The TAiOUT pin outputs a low-level (“L”) signal.
The IR bit in the TAiIC register becomes 1 (interrupt requested) after one CPU clock cycle.
When selecting one-shot timer mode after reset.
When switching from timer mode to one-shot timer mode.
When switching from event counter mode to one-shot timer mode.
When selecting PWM mode after reset.
When switching from timer mode to PWM mode.
When switching from event counter mode to PWM mode.
The counter stops.
If the TAiOUT pin outputs a high-level (“H”) signal, the signal changes to “L” and the IR bit
becomes 1.
If the TAiOUT pin outputs an “L” signal, its output signal and the IR bit remains unchanged.
Timer A (One-Shot Timer Mode)
Timer A (Pulse Width Modulation Mode)
