Table 8–4. Configuration Schemes for Cyclone IV GX Devices (EP4CGX30 [only for F484 package], EP4CGX50,
EP4CGX75, EP4CGX110, and EP4CGX150) (Part 2 of 2)
Configuration Scheme
JTAG-based configuration

Notes to Table 8–4:
(1) Configuration voltage standard applied to the V
(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
Altera recommends connecting the MSEL pins to GND if your device is only using JTAG configuration.

Smaller Cyclone IV E devices or package options (E144 and F256 packages) do not
have the MSEL[3]pin. The AS Fast POR configuration scheme at 3.0- or 2.5-V
configuration voltage standard and the AP configuration scheme are not supported in
Cyclone IV E devices without the MSEL[3]pin. To configure these devices with other
supported configuration schemes, select MSEL[2..0]pins according to the MSEL
settings in
