tCLK: See “(2) Clock Signals.”
*1: When the trigger mode is set for “H” level signal input or RISE-EDGE, a pulse of at least this width is received
as a REQ-FF signal. Note that this rule does not guarantee that no interrupts less than this width will be received.
*2: When the trigger mode is set for “L” level signal input or FALL-EDGE, a pulse of at least this width is received
as a REQ-FF signal. Note that this rule does not guarantee that no interrupts less than this width will be received.
