Notes to Table 8–4:
(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.
1 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 Table 8–5.
