1   Connect the MSEL pins to select the configuration scheme; do not leave them floating.

JTAG configuration is always available, regardless of the MSEL pin selection. The MSEL pins are powered by the VCCPGM power supply of the residing bank. The MSEL[2..0] pins have 25 kΩ internal pull-down resistors that are always active.

During POR and reconfiguration, the MSEL pins must be at LVTTL VIL and VIH levels to be considered a logic low and logic high, respectively. To avoid problems with detecting an incorrect configuration scheme, hardwire the MSEL pins to VCCPGM or GND without pull-up or pull-down resistors. Do not drive the MSEL pins with a microprocessor or another device.
