Configuration Scheme
A configuration scheme with different configuration voltage standards is selected by
driving the
MSEL
pins either high or low, as shown in
, and
.
1
Hardwire the
MSEL
pins to V
CCA
or GND without pull-up or pull-down resistors to
avoid problems detecting an incorrect configuration scheme. Do not drive the
MSEL
pins with a microprocessor or another device.

JTAG-based configuration
—
—
(1) Configuration voltage standard applied to the V
CCIO
supply of the bank in which the configuration pins reside.
(2) JTAG-based configuration takes precedence over other configuration schemes, which means the
MSEL
pin settings are ignored.
(3) Do not leave the
MSEL
pins floating. Connect them to V
CCA
or GND. These pins support the non-JTAG configuration scheme used in production.
Altera recommends connecting the
MSEL
pins to GND if your device is only using JTAG configuration.
