Hot Socketing and Power-On Reset in MAX II Devices
1
After SRAM configuration, all registers in the device are cleared
and released into user function before I/O tri-states are released.
To release clears after tri-states are released, use the DEV_CLRn
pin option. To hold the tri-states beyond the power-up
configuration time, use the DEV_OEpin option.
