2665 - MACHXO2: Are the registers initialized to a known value after a re-configuration operation?

In MachXO2, during normal device power-up, all registers are initialized to zero. The same is true for re-configuration operations.

After re-configuration (e.g. 'REFRESH' command or PROGRAMN pin toggle) the MachXO2 device performs the same initialization process, including Global Reset, to initialize the design registers.

For additional information regarding the power-up and initialization sequence of the MachXO2 device, please refer to TN1204.
