(3) External interrupt falling, rising edge specification register 9H (INTF9H, INTR9H)
Remark
The INTF9H and INTR9H registers are 8-bit registers that specify detection of the falling and rising edges of
the external interrupt pins (INTP4 to INTP6).
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
Caution When switching from the port function to the external interrupt function (alternate function),
Caution Be sure to clear the INTF9n and INTR9n bits to 00 when these registers are not used for the

an edge might be detected. Therefore, set the INTF9n and INTR9n bits to 00, and then specify
the external interrupt function (PMC9.PMC9n bit = 1).
When switching from the external interrupt function to the port function, an edge might be
detected as well. Therefore, set the INTF9n and INTR9n bits to 00, and then specify the port
function (PMC9.PMC9n bit = 0).
