System Integration Module (SIM)
Table 9-8
this table can be any internal interrupt source programmed to the given level and priority. For example,
assume that two internal interrupt sources were programmed to IL[2:0] =110, one having a priority of
IP[1:0] = 01 and one having a priority of IP[1:0] = 10. If both assert an interrupt request at the same time,
the order of servicing would occur as follows:
