(18) Edge detection
(19) External event counter
(20) PPG output
(21) STOP mode or system clock stop mode setting
(22) P21/TI010/TO00 pin
<1> In the following cases, note with caution that the valid edge of the TI0n0 pin is detected.
<2> The sampling clock used to remove noise differs when the valid edge of TI000 is used as the count clock
<1> The timing of the count start is after two valid edge detections.
<2> When reading the external event counter count value, TM00 should be read.
<1> Values in the following range should be set to CR000 and CR010:
<2> The cycle of the pulse generated through PPG output (CR000 setting value + 1) has a duty of (CR010
Except when the valid edge of the TI000 pin is selected as the count clock, stop the timer operation before
setting STOP mode or system clock stop mode; otherwise the timer may malfunction when the system clock
starts.
When using P21 as the input pin (TI010) of the valid edge, it cannot be used as a timer output pin (TO00).
When using P21 as the timer output pin (TO00), it cannot be used as the input pin (TI010) of the valid edge.
Remark n = 0, 1
and when it is used as a capture trigger. In the former case, the count clock is f
the count clock is selected by prescaler mode register 00 (PRM00). The capture operation is not
performed until the valid edge is sampled and the valid level is detected twice, thus eliminating, noise
with a short pulse width.

setting value + 1)/(CR000 setting value + 1).
(a) Immediately after a system reset, if a high level is input to the TI0n0 pin, the operation of 16-bit
(b) If the TM00 operation is stopped while the TI0n0 pin is at high level, TM00 operation is then enabled
(c) When the TM00 operation is stopped while the TI0n0 pin is at low level, TM00 operation is then
timer counter 00 (TM00) is enabled
after a low level is input to the TI0n0 pin
enabled after a high level is input to the TI0n0 pin
If the rising edge or both rising and falling edges are specified as the valid edge of the TI0n0 pin,
a rising edge is detected immediately after the TM00 operation is enabled.
If the falling edge or both rising and falling edges are specified as the valid edge of the TI0n0 pin,
a falling edge is detected immediately after the TM00 operation is enabled.
If the rising edge or both rising and falling edges are specified as the valid edge, of the TI0n0 pin,
a rising edge is detected immediately after the TM00 operation is enabled.
