specification register 1 (INTF1)
The INTR1 and INTF1 registers are used to specify the trigger mode of the INTP08 to INTP13, INTP17, and
INTP18 pins and can specify the valid edge independently for each pin (rising edge, falling edge, or both rising
and falling edges).
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
Caution When the function is changed from the external interrupt function (alternate function) to the
n = 08 to 13, 17, 18
For the valid edge specification, see Table 20-4.

port mode, an edge may be detected. Therefore, be sure to clear the INTFn and INTRn bits to
00, and then set the port mode (n = 08 to 13, 17, 18).
