6.5.5. Remote System Upgrade State Machine
The remote system upgrade control and update registers have identical bit definitions but serve different functions.
Both registers can only be updated when the device is loaded with a factory configuration image. However, the user logic controls the update register writes and the remote system upgrade state machine controls the control register writes.
If there is an error or reconfiguration trigger condition, the remote system upgrade state machine directs the system to load a factory or application configuration (based on mode and error condition) by setting the control register accordingly.
The remote system upgrade status register is updated by the dedicated error monitoring circuitry after an error condition, but before the factory configuration is loaded.
Reconfiguration Error/Trigger | Control Register Setting In Remote Update |
---|---|
nCONFIG reset | All bits are 0 |
nSTATUS error | All bits are 0 |
CORE triggered reconfiguration | Update register |
CRC error | All bits are 0 |
Wd time out | All bits are 0 |
