6.11.5.14 Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS)

There are two unique Programmable Real-Time Unit and Industrial Communication Subsystems (PRU-ICSS0

and PRU-ICSS1) integrated into the device. The programmable nature of the PRU cores, along with enhanced

GPIO access to device pins, system events, and other device resources, provides flexibility in implementing fast

real-time responses, specialized data handling operations, custom peripheral interfaces, and offloading tasks

from other processor cores in the device.

For more details about features and additional description information on the device PRU-ICSS, see the

corresponding subsections within the device specific TRM.

Note

The PRU-ICSS requires a second layer of signal multiplexing in addition to the top-level device pin

multiplexing. Refer to the Environment section of the PRU-ICSS TRM Chapter for additional details.

Note

The generic PRU-ICSS naming and PRU_ prefix is used to represent the signal names for all PRU-

ICSS instances.
