Figure 10.10 IFSR Register

C
External input generates the INTi interrupt (i = 0 to 5). The LVS bit in the INTiIC register selects either edge
sensitive triggering to generate an interrupt on any edge or level sensitive triggering to generate an inter-
rupt at an applied signal level. The POL bit in the INTiIC register determines the polarity.
For edge sensitive, when the IFSRi bit in the IFSR register is set to "1", an interrupt occurs on both rising
and falling edges of the external input. If the IFSRi bit is set to "1", set the POL bit in the corresponding
register to "0" (falling edge).
For level sensitive, set the IFSRi bit to "0" (single edge). When the INTi pin input level reaches the level set
in the POL bit, the IR bit in the INTiIC register is set to "1". The IR bit remains unchanged even if the INTi
pin level is changed. The IR bit is set to "0" when the INTi interrupt is acknowledged or when the IR bit is
written to "0" by program.
Figure 10.10 shows the IFSR register.
