The interrupt sensitivity, defined using the IS1[1:0] bits, is applied to the following
external interrupts:
- ei2 for port B [3:0] (see
- ei3 for port B4 (see
Bits 7 and 6 can only be written when I1 and I0 of the CC register are both set to 1
(level 3).
This bit is used to invert the sensitivity of port B [3:0] 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
The interrupt sensitivity, defined using the IS2[1:0] bits, is applied to the following
external interrupts:
- ei0 for port A[3:0] (see
- ei1 for port F[2:0] (see
Bits 4 and 3 can only be written when I1 and I0 of the CC register are both set to 1
(level 3).
This bit is used to invert the sensitivity of port A [3:0] 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.
