JTAG-based configuration takes precedence over other configuration schemes, which means MSEL pin settings are
ignored. However, the POR time is dependent on the MSEL pin settings.

In some applications, it may be necessary for a device to wake up very
quickly in order to begin operation. The Cyclone III device family offers
the fast POR time option to support fast wake-up time applications. The
fast POR time option has stricter power up requirements compared to the
standard POR time option. You can select either the fast POR option or the
standard POR option using the MSEL pin settings.
For more information on wake-up time, refer to the Hot Socketing and
Power-On Reset in Cyclone III Devices chapter in the Cyclone III Device
Handbook.

Configuration and JTAG Pin I/O Requirements
Cyclone III devices are manufactured using TSMC’s 65-nm low-k
dielectric process. Although Cyclone III devices use TSMC 2.5-V
transistor technology in I/O buffers, the devices are compatible and able
to interface with 2.5V/3.0V/3.3V configuration voltage standards.
However, you must follow specific requirements when interfacing
Cyclone III devices with 2.5V/3.0V/3.3V configuration voltage
standards.
The fast POR time feature in Cyclone III devices is similar to the
Fast-On feature in Cyclone II devices designated with an “A” in
the ordering code.
The Cyclone III devices’ fast wake-up time meets the
requirement of common bus standards in automotive
applications, such as Media Orientated Systems Transport
(MOST) and Controller Area Network (CAN).
