6.4.2 TO0n Pin Output Setting
operation start.
6.4.3 Cautions on Channel Output Operation
210
The following figure shows the procedure and status transition of TO0n out put pin from initial setting to timer
(1) Changing values set in registers TO0,TOE0,TOL0, and TOM0 during timer operation
Remark
Remark
<1> The operation mode of timer output is set.
<2> The timer output signal is set to the initial status by setting TO0n.
<3> The timer output operation is enabled by writing 1 to TOE0n (writing to TO0n is disabled).
<4> The port I/O setting is set to output (see 6.3 (15) Port mode registers 0, 1, 3, 4).
<5> The timer operation is enabled (TS0n = 1).
Since the timer operations (operations of TCR0n and TDR0n) are independent of the TO0n output circuit and
changing the values set in TO0, TOE0, TOL0, and TOM0 does not affect the timer operation, the values can be
changed during timer operation. To output an expected waveform from the TO0n pin by timer operation,
however, set TO0, TOE0, TOL0, and TOM0 to the values stated in the register setting example of each
operation.
When the values set in TOE0, TOL0, and TOM0 (except for TO0) are changed close to the timer interrupt
(INTTM0n), the waveform output to the TO0n pin may be different depending on whether the values are
changed immediately before or immediately after the timer interrupt (INTTM0n) signal generation timing.
• TOM0n bit (0: Toggle mode, 1: Combination-operation mode)
• TOL0n bit (0: Forward output, 1: Reverse output)
