Figure 7-4 Parameter of opto-isolated input circuit
Rising time delay (TRIGIN_R_DELAY): the time required for the response to the decrease to 0.8V of
INPUT0 from 50% rising of LINE0+
Falling time delay (TRIGIN_F_DELAY): the time required for the response to the rise to 2V of INPUT0
from 50% falling of LINE0+
