(4) External interrupt rising, falling edge specification registers 4 (INTR4, INTF4)
Remark
The INTR4 and INTF4 registers are 8-bit registers that specify detection of the rising and falling edges of the
INTP14 pin.
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
Caution Be sure to set the INTF40 and INTR40 bits to 00 if the corresponding pin is not used as the

For the valid edge specification combinations, see Table 18-9.

the port function, an edge may be detected. Therefore, clear the INTF40 and INTR40 bits
to 00, and then set the port mode.
