16 years agoYou don't refer to a particular device. In the Cyclone 3 handbook, I don't see a hint, that MSEL can be controlled dynamically. In contrast, there are many warnings that suggest to hardwire the pins. It's not explicitely said, when MSEL is read respectively latched, but I would rather expect at POR (after VCCA and VCCINT reach the specified level).
It's also said, that nCE must be driven low to use JTAG configuration.
