2: Asynchronous interrupt latency = 3-4 T
3: CLKOUT is available only in INTOSC and RC Oscillator modes.
4: For minimum width of INT pulse, refer to AC specifications in Section 15.0 “Electrical Specifications”.
5: INTF is enabled to be set any time during the Q4-Q1 cycles.
Shaded cells are not used by the interrupt module.
