0 = Interrupt requests from RTI are disabled.
1 = Interrupt is requested when RTI is set.
0 = Allows the RTI and COP to continue running in wait
1 = Disables both the RTI and COP when the part goes into wait
0 = Allows the RTI and COP to continue running while in background mode
1 = Disables RTI and COP when the part is in background mode (useful for
0 = Divider chain functions normally.
1 = Divider chain is bypassed, allows faster testing. The divider chain is
