12.1 Introduction
Several peripherals have direct connections between them, enabling autonomous
communication and/or synchronization between them. This saves CPU resources and,
consequently power consumption. In addition, these hardware connections remove
software latency and result in more predictable system design.
Depending on peripherals, these interconnections can operate in Run, Sleep, LPRun,
LPSleep, Stop 0, Stop 1 and Stop 2 modes.
