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 17.0 “Electrical Specifications”.
5: INTF is enabled to be set any time during the Q4-Q1 cycles.
x = unknown, u = unchanged, — = unimplemented read as ‘0’, q = value depends upon condition.
Shaded cells are not used by the Interrupt module.
