Resets can be described as three groups.
- Device-level resets controlled by hardware and software
- Subsystem resets controlled by software
- Individual block resets controlled by software
The device-level resets include major subsystems that include the LPD and FPD, the NoC interconnect, and other integrated hardware. The device-level resets are generated by the POR_B input pin, the EAM, and the firmware in the PLM and PSM.
The subsystems are affected by the device-level resets and the individual block resets are affected by device and subsystem resets.
