-- Description: This design contains the configuration state machine (SM).     
--                                                                         
-- Note: 
-- 1. 	When max_en is '0' the MAX device will NOT attempt to configure the device
-- 2. 	RESET_n is active low signal to reset flash and FPGA and then configure FPGA.
-- 3.	SM will stop at "STATE_CONF_DONE" state if "Enable INIT_DONE Output" is disabled
-- 		SM will enter "STATE_INIT_DONE" only if "Enable INIT_DONE Output" is enabled
-- 4.	Refer to documentation for details on functionality of this design.
