AM6 Navigator Subsystem Descriptions¶
Introduction¶
This chapter provides information on the Navigator Subsystems in the am6 SoC. Some System Firmware TISCI messages take Navigator Subsystem specific inputs. This chapter provides information on the valid values for applicable TISCI message parameters.
Navigator Subsystem Device IDs¶
Some System Firmware TISCI message APIs require the device ID of the Navigator Subsystem to be modified as part of the request. Based on the AM6 Device IDs these are the valid Navigator Subsystem device IDs.
