9.1
Features
The XE8000 chips support 8 event sources, divided into 2 levels of priority.
9.2
Overview
An event is different from an interrupt in that it does not modify the program counter (PC). Events are used by two
microcontroller instructions.
First of all, events are useful to wake-up the microcontroller when it is in HALT. The software execution then simply
resumes at the instruction next to the HALT instruction. The second instruction is the conditional jump on event
(JEV). The jump is executed if one of the event flags in the stat register is set. In all other cases, the occurrence of
an event has no effect.
The event handler allows 8 event sources to be managed individually. 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 (EV0and IN1; see CoolRisc documentation for more information).
Additional functions are given that allow fast detection of the highest priority event that has been activated.
