(a) Specifying valid edge after reset
(b) Sampling clock for eliminating noise
The signal input to the TI00n/TI01n pin is not acknowledged while the timer is stopped, regardless of the operation
mode of the CPU.
Remarks 1. f
When the valid edge of TI00n is specified as the count clock, the capture register for which TI00n is specified as
a trigger does not operate correctly.
To accurately capture the count value, the pulse input to the TI00n and TI01n pins as a capture trigger must be
wider than two count clocks selected by PRM0n (see Figure 7-9).
The capture operation is performed at the falling edge of the count clock but the interrupt signals (INTTM00n and
INTTM01n) are generated at the rising edge of the next count clock (see Figure 7-9).
When the count value of the TM0n register is captured to the CR00n register in the phase reverse to the signal
input to the TI00n pin, the interrupt signal (INTTM00n) is not generated after the count value is captured. If the
valid edge is detected on the TI01n pin during this operation, the capture operation is not performed but the
INTTM00n signal is generated as an external interrupt signal. Mask the INTTM00n signal when the external
interrupt is not used.
If the operation of the 16-bit timer/event counter 0n is enabled after reset and while the TI00n or TI01n pin is at
high level and when the rising edge or both the edges are specified as the valid edge of the TI00n or TI01n pin,
then the high level of the TI00n or TI01n pin is detected as the rising edge. Note this when the TI00n or TI01n
pin is pulled up. However, the rising edge is not detected when the operation is once stopped and then enabled
again.
The sampling clock for eliminating noise differs depending on whether the valid edge of TI00n is used as the
count clock or capture trigger. In the former case, the sampling clock is fixed to f
selected by PRM0n is used for sampling.
When the signal input to the TI00n pin is sampled and the valid level is detected two times in a row, the valid
edge is detected. Therefore, noise having a short pulse width can be eliminated (see Figure 7-9).
