Introductionsuccessfully. Toggling these pins during user-mode does not affect thedevice operation; however, the MSEL pins must be valid before areconfiguration is initiated.Table 8–1.

Ifonly JTAG configuration is used, you should connect the MSEL pins to ground.(2) JTAG-based configuration takes precedence over other configuration schemes,which means MSEL pin settings are ignored.Tables 8–2 through 8–5 show the approximate configuration file sizes forMercury, APEX 20K (2.5 V), ACEX 1K, and FLEX 10K devices.Table 8–2.
