Interrupts
62/247
Bits 4:3 = IS2[1:0] ei0 and ei1 sensitivity
●
Table 20.
●
Table 21.
These 2 bits can be written only when I1 and I0 of the CC register are both set to 1 (level 3).
Bit 2 = IPA Interrupt polarity for ports A3 and E1
Bits 1:0 = Reserved, must always be kept cleared.

The interrupt sensitivity, defined using the IS2[1:0] bits, is applied to the following
external interrupts:
ei0 (port A3, port E1)
ei1 (port F2..0)
This bit is used to invert the sensitivity of the port A3 and E1 external interrupts. It can
be set and cleared by software only when I1 and I0 of the CC register are both set to 1
(level 3).
0: No sensitivity inversion
1: Sensitivity inversion
External interrupt sensitivity (ei0)
External interrupt sensitivity (ei1)
