(3) External interrupt falling, rising edge specification register 8 (INTF8, INTR8)
Remark
The INTF8 and INTR8 registers are 8-bit registers that specify detection of the falling and rising edges of the
external interrupt pin (INTP8).
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 INTF80 and INTR80 bits to 00 when these registers are not used as INTP8
INTF80
For how to specify a valid edge, see Table 19-5.
2. The INTP8 pin and RXDA3 pin are alternate-function pins. When using the pin as the RXDA3

and then set the port mode.
pin, disable edge detection for the INTP8 alternate-function pin (clear the INTF8.INTF80 bit
and the INTR8.INTR80 bit to 0). When using the pin as the INTP8 pin, stop UARTA3 reception
(clear the UA3CTL0.UA3RXE bit to 0).
