INT0 to INT5 are triggered by the edges of external inputs. The edge polarity is selected using the polarity
select bit.
Of interrupt control registers, 0048
register, and 0049
interrupt request cause select bits - bits 6 and 7 of the interrupt request cause select register (035F
specify which interrupt request cause to select. After having set an interrupt request cause, be sure to clear
the corresponding interrupt request bit before enabling an interrupt.
Either of the interrupt control registers - 0048
to “0” to select an serial I/O as the interrupt request cause.
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
to ‘falling edge’ (“0”).
Figure 1.11.10 shows the Interrupt request cause select register.
