The distributed programmable peripheral interconnect (DPPI) system enables
peripherals to interact autonomously with each other through tasks and events, without
intervention from the CPU.
The DPPI channels are local to each power domain, but can be transferred between power
domains using PPI bridges.
The following figure shows the power domains, the PPI controllers (DPPIC), and the PPI
bridges (PPIB).
Figure 1. Power domains and PPI bridges
A subset of PPI channels from a power domain can be bridged across to a
different power domain. For example, PPIB00 can bridge a set number of configurable DPPI
channels to PPIB10. For more details on how to configure the PPI and bridge system, see
DPPI — Distributed programmable peripheral interconnect and PPIB — PPI Bridge.
