(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 the function is changed from the external interrupt function (alternate function) to the port
Caution Be sure to clear the INTF9n and INTR9n bits to 00 when these registers are not used as INTP4
Remark
INTF9n
For how to specify a valid edge, see Table 19-5.
INTR9H
function, an edge may be detected. Therefore, clear the INTF9n and INTR9n bits to 0, and then
set the port mode.
