polarity select bit.
As for external interrupt input, an interrupt can be generated both at the rising edge and at the falling edge
by setting “1” in the INTi interrupt polarity switching bit of the interrupt request cause select register
(035F
ter to ‘falling edge’ (“0”).
Figure 2.7.10 shows the Interrupt control reserved register, Figure 2.7.11 shows the Interrupt request
cause select register.
