Usage precaution
Usage Precaution
Timer A (timer mode)
(1) Reading the timer A0 register while a count is in progress allows reading, with arbitrary timing, the
value of the counter. Reading the timer A0 register with the reload timing gets “FFFF16”. Reading
the timer A0 register after setting a value in the timer A0 register with a count halted but before the
counter starts counting gets a proper value.
Timer A (event counter mode)
(1) Reading the timer A0 register while a count is in progress allows reading, with arbitrary timing, the
value of the counter. Reading the timer A0 register with the reload timing gets “FFFF16” by under-
flow or “000016” by overflow. Reading the timer A0 register after setting a value in the timer A0
register with a count halted but before the counter starts counting gets a proper value.
(2) When stop counting in free run type, set timer again.
Timer A (one-shot timer mode)
(1) Setting the count start flag to “0” while a count is in progress causes as follows:
The counter stops counting and a content of reload register is reloaded.
The TA0OUT pin outputs “L” level.
The interrupt request generated and the timer A0 interrupt request bit goes to “1”.
(2) The timer A0 interrupt request bit goes to “1” if the timer's operation mode is set using any of the
following procedures:
Selecting one-shot timer mode after reset.
Changing operation mode from timer mode to one-shot timer mode.
Changing operation mode from event counter mode to one-shot timer mode.
Therefore, to use timer A0 interrupt (interrupt request bit), set timer A0 interrupt request bit to “0”
after the above listed changes have been made.
Timer A (pulse width modulation mode)
(1) The timer A0 interrupt request bit becomes “1” if setting operation mode of the timer in compliance
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 A0 interrupt (interrupt request bit), set timer A0 interrupt request bit to “0”
after the above listed changes have been made.
(2) Setting the count start flag to “0” while PWM pulses are being output causes the counter to stop
counting. If the TA0OUT pin is outputting an “H” level in this instance, the output level goes to “L”,
and the timer A0 interrupt request bit goes to “1”. If the TA0OUT pin is outputting an “L” level in this
instance, the level does not change, and the timer A0 interrupt request bit does not becomes “1”.
