48 /* The MEC14xx controller allows interrupts to be aggregated into a single
\r
49 * signal which triggers a single interrupt with a fixed priority for all
\r
50 * interrupt levels. Alternatively the signals can be disaggregated into unique
\r
51 * interrupt events which can be vectored via a dispatch table to unique
\r
52 * handlers for each interrupt source. This mechanism allows, for instance, a
\r
53 * single interrupt handler for a large number of IO pins yet unique handlers
\r
54 * for timers and other signals.
\r
56 * When operating in disaggregated mode certain restrictions apply. The
\r
57 * interrupt event and status registers are shared between timers due to their
\r
58 * proximity in the memory map. Similarly the software interrupt control
\r
59 * registers are shared with other interrupt sources. The JTVIC maps interrupt
\r
60 * levels into MIPs core interrupt levels consequently JTVIC priorities of 0, 1,
\r
61 * 3, and 4 map to the MIPs core values of 1, 3, 5, and 7. The parameter
\r
62 * configTIMERS_DISAGGREGATED_ISRS is used to control if the timers in register
\r
63 * GIRQ23 are operating in disaggregated mode. Similarly
\r
64 * configCPU_DISAGGREGATED_ISRS controls the mode for GIRQ24.
\r
67 * Disaggregated mode is the more natural manner in which to operate the ISRs
\r
68 * and currently only this mode has been tested with the demo application. If
\r
69 * you wish to use aggregated mode then an alternative interrupt handler scheme
\r
70 * will need to be used that marshals all interrupts from a single GIRQ through
\r
71 * a common handler function that tests which interrupt occurred and dispatches
\r
72 * to the relevant handlers.
