Usage Precautions
3.0 Usage
3.1 Usage Precautions
Timer A (timer mode)
Reading the timer Ai register while a count is in progress allows reading, with arbitrary timing, the
value of the counter. Reading the timer Ai register with the reload timing gets “FFFF16”. Reading the
timer Ai register after setting a value in the timer Ai register with a count halted but before the counter
starts counting gets a proper value.
Timer A (event counter mode)
Reading the timer Ai register while a count is in progress allows reading, with arbitrary timing, the
value of the counter. Reading the timer Ai register with the reload timing gets “FFFF16” by underflow
or “000016” by overflow. Reading the timer Ai register after setting a value in the timer Ai register
with a count halted but before the counter starts counting gets a proper value.
When stop counting in free run type, set timer again.
Timer A (pulse width modulation mode)
The timer Ai 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 Ai interrupt (interrupt request bit), set timer Ai interrupt request bit to “0” after
the above listed changes have been made.
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”.
Timer B (timer mode)
Reading the timer Bi register while a count is in progress allows reading , with arbitrary timing, the
value of the counter. Reading the timer Bi register with the reload timing gets “FFFF16”. Reading the
timer Bi register after setting a value in the timer Bi register with a count halted but before the counter
starts counting gets a proper value.
A-D Converter
Write to each bit (except bit 6) of A-D control register 0, to each bit of A-D control register 1, and to
bit 0 of A-D control register 2 when A-D conversion is stopped (before a trigger occurs).
In particular, when the Vref connection bit is changed from “0” to “1”, start A-D conversion after an
elapse of 1 s or longer.
When changing A-D operation mode, select analog input pin again.
Using one-shot mode or single sweep mode
Read the correspondence A-D register after confirming A-D conversion is finished. (It is known by A-
D conversion interrupt request bit.)
Using repeat mode, repeat sweep mode 0 or repeat sweep mode 1
Use the undivided main clock as the internal CPU clock.
