Peripherals

6.2 DPPI - Distributed programmable peripheral

interconnect

The distributed programmable peripheral interconnect (DPPI) enables peripherals to interact

autonomously with each other by using tasks and events, without any intervention from the CPU. DPPI

allows precise synchronization between peripherals when real-time application constraints exist, and

eliminates the need for CPU involvement to implement behavior which can be predefined using the DPPI.

Note: For more information on tasks, events, publish/subscribe, interrupts, and other concepts,

see Peripheral interface on page 15.

The DPPI has the following features:

• Peripheral tasks can subscribe to channels

• Peripheral events can be published on channels

• Publish/subscribe pattern enabling multiple connection options that include the following:

• One-to-one

• One-to-many

• Many-to-one

• Many-to-many

The DPPI consists of several PPIBus modules, which are connected to a fixed number of DPPI channels and

a DPPI configuration (DPPIC).
