JTAG-based configuration
Notes to
(1) Altera recommends connecting the MSEL pins to V
(2) The configuration voltage standard is applied to the V
(3) JTAG-based configuration takes precedence over other configuration schemes, which means the MSEL pin settings are ignored. However, the
POR time is dependent on the MSEL pin settings.

In some applications, it is necessary for a device to wake up very quickly 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 when compared with the standard POR time option. You can select
either the fast POR or standard POR options with the MSEL pin settings.
The automotive application is for Cyclone III devices only. 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).
