The interrupt sensitivity, defined using the IS1[1:0] bits, is applied to the following
external interrupts:
- ei2 (port B3..0) (see
- ei3 (port B7..4) (see
These 2 bits can be written only when I1 and I0 of the CC register are both set to 1
(level 3).
This bit is used to invert the sensitivity of the 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 (port A3..0) (see
- ei1 (port F2..0) (see
These 2 bits can be written only when I1 and I0 of the CC register are both set to 1
(level 3).
This bit is used to invert the sensitivity of the 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
This bit allows to toggle the TLI edge sensitivity. It can be set and cleared by
software only when TLIE bit is cleared.
0: Falling edge
1: Rising edge
This bit allows to enable or disable the TLI capability on the dedicated pin. It is set
and cleared by software.
0: TLI disabled
1: TLI enabled
Note: A parasitic interrupt can be generated when clearing the TLIE bit.
