Nordic VEVIF (VPR Event Interface) - TASK RX MODE
|
||
|
|
|
||
|
|
VEVIF is an event interface for VPR, allowing connection to the domain's DPPI
|
||
|
|
system. VEVIF can also generate IRQs to other CPUs.
|
||
|
|
|
||
|
|
VEVIF provides support for inter-domain software signaling. It implements a set of tasks
|
||
|
|
intended for signaling within an interprocessor communication (IPC) framework.
|
||
|
|
When used in task rx mode, the VEVIF tasks are used to receive events triggered by other core.
