Interrupt mode register 0 (INTM0)
The behaviour of the external interrupt input pins INTP0 to INTP2 can be specified by the interrupt
mode register 0 (INTM0).
The INTM0 register can be read/written in 8-bit or 1-bit units.
Figure 7-15:
Interrupt Mode Register 0 (INTM0)
Caution:
Changing the state of interrupt mode configuration registers ESn0/ESn1 may trigger
an unintended interrupt event for the respective interrupt channels. Be sure to mask
the respective interrupt channel and clear the interrupt status flag after changing the
bits ESn0/ESn1 of the interrupt channel (n = 0 to 2).
After reset:
