Specifications

5.11.5.21 PRU_ICSSG

The device has integrated three identical PRU_ICSSG subsystems (PRU_ICSSG0, PRU_ICSSG1 and

PRU_ICSSG2). The programmable nature of the PRU cores, along with their access to pins, events and

all device resources, provides flexibility in implementing fast real-time responses, specialized data

handling operations, custom peripheral interfaces, and in offloading tasks from the other processor cores

of the device.

For more details about features and additional description information on the device Programmable Real-

Time Unit Subsystem and Industrial Communication Subsystem - Gigabit, see the corresponding sections

within Section 4.3, Signal Descriptions and Section 6, Detailed Description.

NOTE

The PRU_ICSSG_0 and PRU_ICSSG_1 support an internal wrapper multiplexing that

expands the device top-level multiplexing. Signal naming in this section must match the

internal wrapper multiplexing.

For more information, please refer to the Device TRM, Chapter Processors and Accelerators,

Section Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem

- Gigabit (PRU_ICSSG).

5.11.5.21.1 Programmable Real-Time Unit (PRU_ICSSG PRU)

NOTE

The PRU_ICSSG PRU signals have different functionality depending on the mode of

operation. The signal naming in this section matches the naming used in the PRU Module

Interface section in the device TRM.
