Notes to
(1) In remote update mode, the remote configuration block does not update the AnF bit automatically (you can update it manually).
(2) This is the default value of the control register bit.
Control Register Bit
(1)
Table
10–15:
The application-not-factory (AnF) bit indicates whether the current configuration
loaded in the Stratix IV device is the factory configuration or an application
configuration. This bit is set low by the remote system upgrade circuitry when an
error condition causes a fall-back to the factory configuration. When the AnF bit is
high, the control register access is limited to read operations. When the AnF bit is low,
the register allows write operations and disables the watchdog timer.
In remote update mode, the factory configuration design sets this bit high (1'b1) when
updating the contents of the update register with the application page address and
watchdog timer settings.

Remote System Upgrade Status Register
The remote system upgrade status register specifies the reconfiguration trigger
condition. The various trigger and error conditions include:
■

Cyclic redundancy check (CRC) error during application configuration
nSTATUS assertion by an external device due to an error
Stratix IV device logic array triggered a reconfiguration cycle, possibly after
downloading a new application configuration image
External configuration reset (nCONFIG) assertion
User watchdog timer time-out
