(1) To clear reset, the count start flag is set to “0”. Set a value in the timer Ai register, then set the

flag to “1”.

(2) The timer Ai interrupt request bit becomes “1” if setting operation mode of the timer in compli-

ance with any of the following procedures:

• Selecting PWM mode after reset.

• Changing operation mode from timer mode to PWM mode.

• Changing operation mode from event counter mode to PWM mode.

Therefore, to use timer Ai interrupt (interrupt request bit), set timer Ai interrupt request bit to

“0” after the above listed changes have been made.

(3) Setting the count start flag to “0” while PWM pulses are being output causes the counter to

stop counting. If the TAiOUT pin is outputting an “H” level in this instance, the output level

goes to “L”, and the timer Ai interrupt request bit goes to “1”. If the TAiOUT pin is outputting an

“L” level in this instance, the level does not change, and the timer Ai interrupt request bit does

not becomes “1”.
