(j) External interrupt rising edge specification register 9H (INTR9H)
This is an 8-bit register used to specify detection of the rising edge for the external interrupt pin.
This register can be read and written in 8-bit or 1-bit units.
2. An on-chip circuit for eliminating noise through analog delay is provided for
