1.8.8 Interprocessor Communication (IPC)
Interprocessor Communication module has 32 interrupt sources. Each source has a set of Enable, Disable, Clear, Set, Mask and Status registers. The interrupt sources are ORed and the IPC interrupt output line is connected to the interrupt controller input.
Using the Library
This library is used to configure 32 interrupt sources IRQ0 to IRQ31. Each source can be enabled or disabled using Enable/DisableIRQ function. Also, it is possible to set the interrupt source using SetIRQ function and clear th einterrupt source using ClearIRQ function.
Library Interface
Peripheral library provides the following interfaces:
