0 = Interrupt requests from RTI are disabled.
1 = Interrupt will be requested whenever RTIF is set.
0 = Allows the RTI and COP to continue running in wait.
1 = Disables both the RTI and COP whenever the part goes into
0 = Allows the RTI and COP to continue running while in
1 = Disables both the RTI and COP when the part is in background
