Notes to
(1) In Cyclone III devices, the CRC_ERROR pin is a dedicated output by default. Optionally, you can enable the CRC_ERROR pin as an open-drain
(2) AP configuration is for Cyclone III devices only.

4-bit configuration input that sets the Cyclone III device
family configuration scheme. These pins must be hardwired
to V
pull-down resistors that are always active.
Some of the smaller devices or package options of
Cyclone III devices do not have the MSEL[3] pin; therefore,
the AP configuration scheme is not supported.
Configuration control input. Pulling this pin low with external
circuitry during user mode causes the Cyclone III device
family to lose its configuration data, enter a reset state, and
tri-state all I/O pins. Returning this pin to a logic-high level
starts a reconfiguration.
The Cyclone III device family drives nSTATUS low
immediately after power-up and releases it after the POR
time.
■
■
Driving nSTATUS low after configuration and initialization
does not affect the configured device. If you use a
configuration device, driving nSTATUS low causes the
configuration device to attempt to configure the device, but
because the device ignores transitions on nSTATUS in user
mode, the device does not reconfigure. To start a
reconfiguration, nCONFIG must be pulled low.
Status output. If an error occurs during configuration,
nSTATUS is pulled low by the target device.
Status input. If an external source (for example, another
Cyclone III device family) drives the nSTATUS pin low
during configuration or initialization, the target device
enters an error state.
