(3) External interrupt falling, rising edge specification register 3 (INTF3, INTR3)
Remark
The INTF3 and INTR3 registers are 8-bit registers that specify detection of the falling and rising edges of the
external interrupt pin (INTP07 to INTP09).
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 port
Caution Be sure to set the INTF3n and INTR3n bits to 00 when these registers are not used as the

For how to specify a valid edge, see Table 23-7.
function, an edge may be detected. Therefore, set the INTF3n and INTR3n bits to 00, and then set
