Table 2-8. Interrupt Priority

*With the exception of the power-fail interrupt, all interrupts require that the IGE bit be set to 1 to generate an interrupt request,

regardless of the individual interrupt enable listed. The power-fail interrupt is not governed by IGE (i.e., interrupt request genera-

tion is controlled solely by the PFIE enable bit).
