Figure 5.6 shows the IWPFn setting timing.
The vector number for the WKP7 to WKP0 interrupt exception handling is 108. Eight interrupt
pins are assigned to one vector number. Accordingly, determine the source using an exception
handling routine.
The detection of interrupts WKP7 to WKP0 does not depend on whether the relevant pin has been
set for input or output. However, when a pin is used as an external interrupt input pin, do not clear
