Configuration
Configuration Scheme
A configuration scheme with different configuration voltage standards is selected by
driving the MSEL pins either high or low, as shown in Table 8–3, Table 8–4, and
Table 8–5.
1 Hardwire the MSEL pins to VCCA 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.

Notes to Table 8–3:
(1) Configuration voltage standard applied to the VCCIO 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 VCCA 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.
