Detailed description
The CoolRISC core has 2 different event levels EV0 and EV1 (Figure 9-1).
The setting and clearing of these events can be done in the stat register (see chapter describing the CPU).
The event handler bundles a certain number of event sources and routes them to one of these two events and
provides the possibility to enable/disable each of them individually. The definition of the event sources is given in
the memory mapping chapter.
RegEvn is an 8-bit register containing flags for the event sources. Those flags are set when the event is enabled
(i.e. if the corresponding bit in the registers RegEvnEn is set) and a rising edge is detected on the corresponding
event source.
Once memorized, writing a ‘1’ in the corresponding bit of RegEvn clears an event flag. Writing a ‘0’ does not modify
the flag. All interrupts are automatically cleared after a reset.
Two registers are provided to facilitate the writing of event service software. RegEvnPriority contains the number
of the highest event set (its value is 0xFF when no event is memorized). RegEvnEvn indicates the priority level of
the current events.
All event sources are sampled by the highest frequency in the system. A CPU event is generated and memorized
when an event becomes high. The 8 event sources are divided into 2 levels of priority: High (4 event sources) and
Low (4 event sources). Those 2 levels of priority are directly mapped to those supported by the CoolRisc (EV0 and
EV1; see CoolRisc documentation for more information).
