(2) 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 (INTP7).
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
Cautions 1. When the function is changed from the external interrupt function (alternate function) to the
Caution Be sure to clear the INTF31 and INTR31 bits to 00 when these registers are not used as INTP7
INTF31
For how to specify a valid edge, see Table 19-4.
2. The INTP7 pin and RXDA0 pin are alternate-function pins. When using the pin as the RXDA0

pin, disable edge detection for the INTP7 alternate-function pin (clear the INTF3.INTF31 bit
and the INRT3.INTR31 bit to 0). When using the pin as the INTP7 pin, stop UARTA0 reception
