Notes 1.
T
smp0
: Timer 0 count clock cycle
However, T
smp0
= 4/f
XX
when TI0n is used as an external clock.
2.
T
smpp
: Digital noise elimination sampling clock cycle of TIP0m pin
If TIP00 is used as an external event count input or an external trigger input, however, T
smpp
= 0 (digital
noise is not eliminated).
Remarks 1.
n = 00, 01, 10, 11, 20, 21, 30, 31
m = 0, 1
2.
The above specification shows the pulse width that is accurately detected as a valid edge. If a pulse
narrower than the above specification is input, therefore, it may also be detected as a valid edge.
