Version
For MAX V devices, the POR circuitry does not monitor the V
levels after the device enters user mode. If there is a V
during user mode, the functionality of the device is not guaranteed and you must

After SRAM configuration, all registers in the device are cleared and released into
user function before the I/O tri-states are released. To release clears after the tri-states
are released, use the DEV_CLRn pin option. To hold the tri-states beyond the power-up
configuration time, use the DEV_OE pin option.
