Timer mode
Event counter mode
One-shot timer mode
The value of the counter can be read, with arbitrary timing, by reading the Timer Ai register while a count is in progress.
Reading the Timer Ai register with the reload timing gets "FFFF
After setting a value in the Timer Ai register, a proper value can be read with the counter stopped before it starts counting

The value of the counter can be read, with arbitrary timing, by reading the Timer Ai register while a count is in progress.

After setting a value in the Timer Ai register, a proper value can be read with the counter stopped before it starts counting .
Reset the timer when counting has stopped in free run type.
If using "Free-Run type", the timer register contents may be unknown when counting begins. Set the timer value
immediately after counting has started.
Example if the up/down count is not switched:
• Enable the "Reload" function and write to the timer register before counting begins.
• Rewrite the value to the timer register immediately after counting has started.
• If counting up, rewrite "0000
• If counting down, rewrite "FFFF
Example if the up/down count is switched:
• Use the "Reload type" operation until the first count pulse is input.
• Switch to "Free-Run type".
Setting the count start flag to "0" while a count is in progress causes as the following:
• The counter stops counting and a content of reload register is reloaded.
• The TAi
• The interrupt request generated and the Timer Ai interrupt request bit goes to"1".
The output from the one-shot timer synchronizes with the count source generated internally. Therefore, when an
external trigger has been selected, a delay of one cycle of count source (maximum) occurs between the trigger input to
