7.1.1 Event System (EVSYS)

The PIC32CM Event System (EVSYS) allows autonomous, low-latency, and configurable direct communication between peripherals. This is often used to reduce CPU load for efficient event-driven applications.

The following are key features of the EVSYS:

• Hardware Event Routing—Direct peripheral communication through hardware events, bypassing the CPU for real-time, low-latency operation
• Configurable Event Channels—Route signals between peripherals
• Flexible Source and User Selection
• Synchronous and Asynchronous Events
• Low Power Operation
• CPU Offload—Reduces CPU intervention for routine tasks, improving efficiency and lowering power consumption
